This chapter describes how humans perceive the world surroundings by means of five senses (Hear, see, smell, taste, and touch), how a system of five senses called Indriya Pancha-Panchaka works and communicates with mind to perceive the surroundings and how a person can maintain health by using his/her senses properly (and therefore leading a tempered, ethical life) or suffer from disease by not using their senses properly. It also explains the role of mind, intellect and soul in the entire process of perception. This chapter describes the qualities of the mind based on the predominance of the three fundamental qualities, the triguna (sattva, rajas and tamas), including the illusions created by the mind that makes a common observer perceive through his/her senses, say, multiple minds instead of one. It further describes the spiritual elements (Adhyatma dravya guna samgraha) & their action. The principles of psycho-pathogenesis based on the excessive, deficient and perverted association of five senses with their objects along with the principles of preventing psychic disturbances and preserving the physical, mental and socio-spiritual health in the form of the principles of sadvritta are elaborately described. This involves a broad range of ethical observances & moral practices for preventing psychosomatic disturbances. Broadly, the practices regarding code of general ethics, diet, natural urges, relationship with women, study, regarding self-control & related to worship are elaborately described. General ethical practices related to individual, inter- personal & about maintenance of social relations have been included, which are extremely valuable for personal & social health.
Keywords: Pancha-panchaka, indriya, manas, sadvritta, Adhyatma dravya guna samgraha, mind, senses, soul, psychology, behaviour therapy, psycho pathology, psycho spiritual aspect, super sense, psychological trait.
In earlier chapters dealing with preventive & promotive aspects of health, the principles related to diet , regimens of daily and seasonal routine, have been described. The mind transcends all the sensory faculties that are merely responsible for receiving and transmitting information about their respective external objects. Without the mind, senses cannot perceive their respective objects. In the present chapter, through a study of the mind and the senses, ethical & moral principles of behaviour & conduct have been explained. The senses act as instruments for the mind to express itself as well as for the soul to acquire knowledge. Senses are controlled by the mind, which is further controlled by buddhi (intellect) and ultimately by atma (soul). Thus this chapter deals with indriya, sattva (mind) and atma (soul).
The fundamental system of pancha- panchaka in reference to the perception of sensory objects is also elucidated. This comprises of five sense faculties, five material constituents corresponding to the five sense faculties, five sense organs, five sense objects and five sense perceptions. All the five components of a particular indriya (sense organs) are inter-related. All the senses work under the coordination of mind. The mind possesses quality of being atindriya i.e. it transcends all the five sense faculties and at the same time and yet is different from those faculties.
The mind does not have constituent elements like senses. Further, the function of the indriya (sense organs) is limited only to its specific sense but the mind has generalised action to every sense. An object can only be perceived by the mind. The ethical and moral principles of life described under sadvritta are the essence of preventive and promotive aspects of health. They train and guide the senses and mind towards better and healthy living, thus promoting sensorial and mental health. They also promote peaceful, happy, prosperous and a more fulfilling life, thereby promoting spiritual health. Some of these principles and directions are intended to protect one’s astral body from getting affected by extra-sensorial evil elements or negative energies like pishacha (evil sprites), rakshasa (demons) etc. These principles may not seem applicable in today’s society due to the changes in contemporary thinking, civilization and social culture since the time of writing of this text, though researches can provide more evidences about their applications.
The sadvritta or ethical observances consist of self-control and proper activities. It includes self-reliance, auto suggestions and physical, mental, verbal and all sorts of activities in daily life along with an ability to discern and exercise control over suppressible and non- suppressible urges. So, the principles of good conducts (sadvritta) aim to preserve all dimensions of health. It also provides unique insights into the correct way of managing life and health. It considers the man as a social organism. His relationship with society is very important from the standpoint of life and health. Therefore, practice of virtues and behaviour in accordance to prevalent social traditions is imperative for the prevention of diseases and promotion of good health. Diseases have their origin in mind. All diseases are due to prajnaparadha (pragyaparadha, or Intellectual defect) as the direct cause, but it is also influenced by excessive, deficient and improper association of senses with their objects (asatmyendriyartha), which is described in this chapter. In a nutshell, this chapter describes unique ways and means of preventing diseases, preserving personal and social health, and leading a productive and useful social life.

There are five sense organs, five (types of) matters of sense organs, five (different) sites of sense organs, five sense objects and five (types of) sensory perceptions, thus said in the context of sense organs. 
Functions of Sattva and Mana as indriya
Super-sensuality of mind
अतीन्द्रियं पुनर्मनः सत्त्वसञ्ज्ञकं, ‘चेतः’ इत्याहुरेके, तदर्थात्मसम्पदायत्तचेष्टं चेष्टाप्रत्ययभूतमिन्द्रियाणाम्||४||

atIndriyaM punarmanaH sattvasa~jj~jakaM, ‘cetaH’ ityAhureke, tadarthAtmasampadAyattaceShTaM ceShTApratyayabhUtamindriyANAm||4||
Mind transcends the sense organs. It is termed as sattva, while some others call it as chetas. Its action is dependent on its objects and accomplishments of the Self i.e. atman or atma. It is responsible for the actions of the sense organs. 
Cause of diverse manifestations of one and same mind

In a single person, mind seems to be numerous because of variations in its own objects, objects of sense organs, its analytical activity related to quickly moving and making its contact with different sensory organs and also due to its inherent connection with the qualities of rajas, tamas and sattva, but in reality it is one. Mind being one, there is no contact with more than one sense organ at a time and therefore there is no simultaneous activity of all the sense organs. 
Determination of Psychological Trait

The sages describe the mind according to the predominance of the guna (quality or predisposition), which is predominantly and repeatedly represented in the mind of a person. 
Perception by Association of Mind and Sense Organs
The sense organs are capable of perceiving objects only when they are associated with the mind. 
Detail description of Indriya pancha-panchaka (Five pentads of sense organs)
Five sense organs
तत्र चक्षुः श्रोत्रं घ्राणं रसनं स्पर्शनमिति पञ्चेन्द्रियाणि||८||
Tatra cakṣuḥ śrōtraṁ ghrāṇaṁ rasanaṁ sparśanamiti pañcēndriyāṇi||8||
tatra cakShuH shrotraM ghrANaM rasanaM sparshanamiti pa~jcendriyANi||8||
The five sense organs are-visual, auditory, olfactory, gustatory and the tactile.
Origin of five sense matters

The five (different) sites of sense organs are- eyes, ears, nose, tongue and skin. 
Five sense objects
The five sense objects are – shabda (sound), sparsha (touch), rupa (vision), rasa (taste) and gandha (smell). 
Five sensory perceptions
पञ्चेन्द्रियबुद्धयः- चक्षुर्बुद्ध्यादिकाः; ताः पुनरिन्द्रियेन्द्रियार्थसत्त्वात्मसन्निकर्षजाः, क्षणिका, निश्चयात्मिकाश्च, इत्येतत्पञ्चपञ्चकम्||१२||

The five (types of ) sensory perceptions are- visual perception etc. They are produced in conjunction with the senses, sense objects, mind and the self (atman). They are momentary and determinative. The five pentads are thus described. 
Adhyatma dravya guna samgraha (substances and qualities pertaining to soul)
मनो मनोर्थो बुद्धिरात्मा चेत्यध्यात्मद्रव्यगुणसङ्ग्रहः शुभाशुभप्रवृत्तिनिवृत्तिहेतुश्च, द्रव्याश्रितं चकर्म; यदुच्यते क्रियेति||१३||

mano manortho buddhirAtmA cetyadhyAtmadravyaguNasa~ggrahaH shubhAshubhapravRuttinivRuttihetushca, dravyAshritaM  ca karma; yaducyate kriyeti||13||
In brief, the substances and qualities pertaining to self (atman) comprise of – the mind, objects of the mind, intellect and the self. This entire set is responsible for an individual’s proclivity towards and abstinence from auspicious and inauspicious acts respectively. Actions also known as therapeutic measures are dependent on substance.
Specific constituents and subjects of sense organs
तत्रानुमानगम्यानां पञ्चमहाभूतविकारसमुदायात्मकानामपि सतामिन्द्रियाणां तेजश्चक्षुषि, खं श्रोत्रे, घ्राणे क्षितिः, आपो रसने,स्पर्शनेऽनिलो विशेषेणोपपद्यते| तत्र यद्यदात्मकमिन्द्रियं विशेषात्तत्तदात्मकमेवार्थमनुगृह्णाति, तत्स्वभावाद्विभुत्वाच्च||१४||

The extant sense organs, which are comprehensible by inference, are composed of the (various) combinations of the five mahabhuta (or basic elements). There is a predominance of tejas in the eyes, akasha in ears, prithvi in nose, apa in tongue and vayu in skin sense organs. Thus, the sense organs perceive their objects according to the predominance of their constituent mahabhuta because of the similarity of their inherent nature (svabhava) and specific capability of sense perception (vibhu) . 
Causes of abnormal and normal sensations
तदर्थातियोगायोगमिथ्यायोगात् समनस्कमिन्द्रियं विकृतिमापद्यमानं यथास्वं बुद्ध्युपघाताय सम्पद्यते, सामर्थ्ययोगात् पुनः प्रकृतिमापद्यमानं यथास्वं बुद्धिमाप्याययति||१५||
Tadarthātiyōgāyōgamithyāyōgāt samanaskamindriyaṁ vikr̥timāpadyamānaṁ yathāsvaṁbuddhyupaghātāya sampadyatē, sāmarthyayōgāt punaḥ prakr̥timāpadyamānaṁ yathāsvaṁbuddhimāpyāyayati||15||

Skewed (excessive, deficient and improper) association of senses with their objects of focus, together with the mind, leads to abnormal sensations and emotions, while proper association returns such sensations to normalcy. 
Functions of mind and preservation of mental health
Object of mind
मनसस्तु चिन्त्यमर्थः| तत्र मनसो मनोबुद्धेश्च त एव समानातिहीनमिथ्यायोगाः प्रकृतिविकृतिहेतवो भवन्ति||१६||
Manasastu cintyamarthaḥ| tatra manasō manōbuddhēśca ta ēva samānātihīnamithyāyōgāḥ prakr̥tivikr̥tihētavō bhavanti||16||
manasastu cintyamarthaH| tatra manaso manobuddheshca ta eva samAnAtihInamithyAyogAH prakRutivikRutihetavo bhavanti||16||
The object of the mind is to think. Proper and improper (excessive, deficient and deviant) association of mind and its ultimate perception (mano-buddhi) causes normal and abnormal perceptions respectively. 
Preservation of normal mind
तत्रेन्द्रियाणां समनस्कानामनुपतप्तानामनुपतापाय प्रकृतिभावे प्रयतितव्यमेभिर्हेतुभिः; तद्यथा सात्म्येन्द्रियार्थसंयोगेनबुद्ध्या सम्यगवेक्ष्यावेक्ष्य कर्मणां सम्यक् प्रतिपादनेन, देशकालात्मगुणविपरीतोपासनेन चेति| तस्मादात्महितं चिकीर्षता सर्वेण सर्वं सर्वदा स्मृतिमास्थाय सद्वृत्तमनुष्ठेयम्||१७||

One should always make efforts to maintain normalcy of sense organs with mind and protect them from any kind of trauma. This can be achieved by proper association of sense organs and their objects, performance of duties after duly considering their pros and cons with the help of the intellect together with the sense faculties and by following (preventive) measures opposite to the qualities of place, season and one’s own constitution. So all, who are desirous of their own well-being, should always remember and abide by all the codes of conduct (described in the following verse).

Now, summing up the contents of the chapter, In this chapter , “the description of the sense organs”, the five pentads and four etiological factors and the code of good conduct have been fully described. One who follows the code of good conduct for the maintenance of positive health lives for a hundred years without any abnormality. Such persons, praised by the noble ones, earn fame all over the world, attain virtue and wealth, friendship of all living beings and at the end, with holy acts, attain the excellent abode (virtuous world) of good souls after the death. Hence this code of conduct should be followed by everybody. Even if something has not been stated here, but prescribed elsewhere as a virtuous act, is also acceptable to Lord Atreya. [30-34]

Tattva Vimarsha (Fundamental Principles)
- The five pentads of sense organs (indriya pancha-panchaka) include sense organs, source material constituent, site, object, and specific perception. These five components are involved in every knowledge process.[verse 3]
- Mind is super-sensual having extra-ordinary capacity to transcend any sense organ. Mind is only one, though it can behave in different ways depending upon specific self constraint, object, and goal oriented activities. Only one object can be perceived at a time by association of mind. Mind has complete control over all senses. The sense organs cannot perceive knowledge without association of mind. The psychological trait is decided by predominance of sattva, rajas and tamas. [verse 4-6]
- The momentary contact of sense organs with their objects in the system of pancha-panchaka leads to specific and definite perception and knowledge of that object. [verse 7-12]
- The group of qualities pertaining to atman (self) including mind, its object [i.e. what it conceives], and intellect decide the good and bad, auspicious and inauspicious acts. Therefore activity or behavior of a person is defined by this group. [verse 13]
- The deficient, excess or improper indulgence of senses in their objects and their association with mind is hazardous for mental health and leads to various disorders.[verse 15]
- The object of mind is to think and to conceive. The proper conception leads to proper activity and improper conception leads to diseases.[verse 16]
- Mental health can be preserved and protected by proper association of sense organs and their objects, performance of duties after duly considering their pros and cons with the help of the intellect together with the sense faculties and by following (preventive) measures opposite to the qualities of place, season and one’s own constitution. So all, who are desirous of their own well being should always remember and follow all principles of code of conduct.[verse 17]
- These do’s and don’ts for positive mental health include codes for eating behavior, personal hygiene, sexual hygiene, behavior with women and with preceptors. It also describes methods and time for learning and studying, codes for normal productive psyche, auspicious deeds, principles for time management in society. [verse 18-28]
- Positive health can be achieved by following keys: Brahmacharya (celebacy), jnana (knowledge), dana (charity), maitri (friendship), karunya (compassion), harsha (happiness), upeksha (detachment) and prashama (peace). One who assiduously follows these prescriptions is devoid of all diseases, lives for a hundred years and does not suffer from untimely death. [verse 29-33]
Vidhi Vimarsha (Applied Inferences)
Table 1: Systematic presentation of pancha-panchaka
|Indriya (Sense Organ)||Indriya Dravya||Indriya Adhishthan (Site of Sensation)||Indriya Artha (Sense Object)||Indriya Buddhi (Sensory Perception)|
|Chakshu (Visual)||Tejas – Jyoti||Eyes||Rupa (Vision)||Visual Perception|
|Shrotra (Auditory)||Kha – Akasha||Ear||Shabda (Sound)||Auditory Perception|
|Ghrana (Olfactory)||Bhu – Prithvi||Nose||Gandha (Smell)||Olfactory Perception|
|Rasanam (Gustatory)||Apa – Jala||Tongue||Rasa (Taste)||Gustatory Perception|
|Sparshanam (Tactile)||Vayu||Skin||Sparsha (Touch)||Tactile Perception|
This pancha-panchaka system [table 1] reveals that senses are the instruments for knowledge of material in external world. All things are constituted by pancha mahabhuta (five elements). Specific sense can perceive the object related to its own basic constituent due to tulyayonitva (similarity in origin and action). E.g. The eyes can see external tejas mahabhuta and perceive the visual sensation only. The continuous interaction is carried out between external materialistic world and internal world (within body) comprising sense perceptions, mind, intellect and soul. The details about sense organs and their interaction with mind are described further in first chapter of Sharira Sthana (section of anatomy and physiology).
Impact of thought/behaviour/ conduct with immunity and health
The behavioural and ethical components of life have direct impact on the health of an individual. It is now known that our thoughts cannot only create or change our mood, but they can actually change our bio- chemistry. We also know that they affect how we see ourselves and the world around us. We also know that our thoughts can affect our physiology.
The development of neuro-psycho-immunobiology has already contributed important understandings to this fundamental idea of Ayurveda. It is also known that when we have positive thoughts we create positive neurochemical messages that are released not only into local brain tissues but to the entire body. Therefore the code of conduct has a direct effect on our psyche and in turn can affect mental health.
Guidelines for sattvavajaya chikitsa and avoidance of pragyaparadha
Mind is the link between atman (soul), indriya and sharira (senses and body). It is responsible for the pravritti (indulgence) and nivritti (non -indulgence) in health promoting and health-degrading activities (shubha or ashubha karmas) because thinking is the object of manas. Samayoga (proper association) of these leads to fruitful results and atiyoga (excessive correlation), hinayoga (deficient/no correlation) and mithyayoga (perverted correlation) leads to dreadful consequences. The sattvavajaya treatments (restraining senses from harmful objects by controlling mind) form important component for psychiatric and psycho-somatic disorders.
Sadvritta (conduct, behavior and moral principles): Key to positive health
Sadvritta trains the mind towards peaceful, prosperous and healthy living. The code of conduct can be broadly divided into two categories by objectives viz.,
- Personal hygiene with personality development
- Social hygiene with healthy social interactions and public victory
Thus the entire chapter focuses on and represents one of the fundamental principles of Ayurvedic science that qualitative and quantitative aspects of the thoughts, attitudes, conduct, behaviour and morality in life are directly related to preventive and promotive aspects of health also with cure of diseases.
Development of modern science in view of psychosomatic aspect of health
It took approximately four centuries for the modern science to understand the real science behind the psychosomatic interaction and to incorporate the principles of psychosomatic approach in understanding of life, health and disease, which is the most fundamental consideration in Ayurvedic system of medicine. Perhaps, a basic mistake occurred during the early phases of development of modern science because of overemphasis on analytical method of reasoning as the scientific process by renowned French philosopher and brilliant mathematician, Rene Descartes (1614 AD). His metaphysical journey resulted into his most famous assertion that the body and mind are separated into two entirely different branches of worldly existence. This Cartesian division between body and mind exerted a profound effect on western thought and it was this approach which has been held-up by protagonists of conventional science till recently in an assiduous manner. In contrast, Ayurveda has strongly proclaimed that the body and mind intimately exist, interact, mutually - influence at each and every level of their worldly existence. In fact, it went on propounding that there is no physical reality in a living being which can be thought of as being devoid of this reciprocal influence. The recent advancements in modern science in 20th century especially in the areas of Neurosciences, molecular biology, biochemistry, bio-technology, immunology have proved beyond doubt that thoughts, emotions, feelings and perception exert direct influence on the bodily functions and the immune response. The vast volume of data from research findings are so convincing that it has led to a new branch of modern Science- ‘Psychoneuroimmunology ’ . It has led to substantiation of age old Ayurvedic principles and proved beyond doubt that fundamentals of Ayurveda are eternal and are based on strong scientific footings.
Psychoneuroimmunology – Evidence based support to Ayurvedic fundamentals and psychosomatic interaction
Psychoneuroimmunology, often referred to as PNI, is the study of interactions between ones perception of the world around him, his behaviour, the way his brain and immune system functions. The field of PNI studies the measurable interaction between psychological and physiological processes. The psychological portion is the psycho aspect, the central nervous system aspect is the neuro aspect, there is an endocrine system aspect, and the body's defense against external infection and aberrant cell division is the immunology aspect.
A group of scientists from many disciplines working on psycho-neuroimmuno-biology, have transcended the past linear approach of Western medicine, but not with the intention of destroying it. They are adding a new and much needed dimensions to the practice of medicine, they are integrating mind and body and in many cases mind, body and spirit. Fridjof Capra, in his books the Tao of Physics and the Turning Point, refers to this movement as a "new paradigm." He suggests that it is acting on all of Western society. Capra includes not only physics and medicine, but also psychology, economics, politics, and even reality itself.
Changing paradigms of disease & health
This new study of the body, mind and spirit connection is demonstrating that there are some dramatic new ways of looking at wellness and illness. One of the areas which is becoming very meaningful is the role of thought and stress on the immune system and the physiology of the body. The role of specific events on blood pressure and other body physiology can be better understood now. The effect of prayer and visual imagery on the course of an illness has been studied well. Through this it can be said that multiple internal factors are involved in the creation of illness, healing and maintenance of wellness. Illness is no longer simply an extension of the germ theory--our present concept of infection being the end result of exposure to a germ, but is expanded to include the ability of the body and its immune system to resist and destroy invading organisms, the stress mechanism, the environment, nutrition and all those factors that are involved with defending and protecting our self from illness.
It is rapidly becoming clearer that most illnesses have a mental or thought component aspect to them. A conflict exists which is not only associated with the illness itself, but frequently is part of the cause of the illness. Psychoneuroimmunology(PNI) appears to go beyond the present narrow biological perspectives of illness to consider behavioural components as an integral part of health and disease. The conceptualization of the role of human behaviour and how it interacts with the central nervous system and the immune system are central issues. Psychoneuroimmunology is thus an arena in which questions about the mind, body and person in context of each other come into the consideration. Thus the principles narrated in the chapter can have a great impact on health and course, severity of illness. This can be researched on the axis of PNI.
Mind-Body-Immune system interaction
Today the immune system is no longer regarded as autonomous and separate from the mind and external events. With the emergence of Psychoneuroimmunology ( PNI), the rise of a new paradigm relating to the practice of medicine can be seen. This new paradigm for the first time integrates the previously dualistic concepts of mind and body. It introduces a new concept where mind and body interact as one, each affecting the other. To date, evidence regarding this mind-body-immune system interaction has been collected with regard to the role of nerve fibers in lymphatic tissues, the sympathetic and parasympathetic nervous systems, the effects of brain lesions on the immune system, the interplay of neurotransmitters, hormones and immune-transmitters. It is being used in research and treatment of AIDS, cancer and bacterial and viral infectious processes. Other researchers are looking at its effects in classic learning and conditioning, the development of the immune system, the impact of experimental and naturally occurring stressors on the immune system, the immune modulating effects of personality characteristics, life style and psychodynamic processes. In the future, research will likely be extended into many new areas including psychotherapy, illness prevention and healing etc. The mind body interaction through the means of indriya has been emphasized in the present chapter.
Tridosha concept and mind– The findings that the messenger chemicals producing desired changes in the biological system can be seen clearly in the tridosha (humoral) concept. Man was seen as responding to interaction of various humors. They accounted for changes in emotion, anger, rage, love, caring, melancholia, depression, humour and for illness. Almost anything could happen when the humors were out of balance. While these humors did not entirely answer what we needed to know, they were an attempt to understand how and why we acted the way we did. The research findings especially in the area of PNI have proved that blending of the interaction of many chemical, electric and other processes that ultimately make the sum total of who and what we are is done. We have come a long way since belief in the humoral concepts of healing, yet as things often have a tendency to make complete circles, we are now once again recognizing that we are not linear but rather a more integrated or holistic. The psycho-neuro-endocrine axis can be focused to study the link between thoughts, behaviours, attitudes, emotions on three dosha.
Scope for further research
- There is much scope to study the effect of sadvritta in improving health of a diseased person in terms of reduction in severity, duration of treatment, and dose of medicines as well as prevention of various diseases.
