''Mahat'' and ''artha'' are two synonyms that indicate ''hridaya'' (heart), used in this context exclusively in the literature related to medical science and not elsewhere. After the description of ''hridaya'' and the ten great vessels that originate there and elaborating further on ''ojas, shira, dhamani, strotas,'' etc., it further describes ''Ayu'' and the difference between happy, unhappy, beneficial, and non-beneficial kinds of life. These were briefly mentioned in the first chapter, but here these have been elaborated. The estimation of the lifespan of an individual when unexpected signs and symptoms appear and the role of self-realization and nonviolence in enhancing the longevity of life has been elaborated. Questions like ‘Why is [https://en.wikipedia.org/wiki/Ayurveda Ayurveda] eternal?’ have been taken up in this chapter. Since this is the last chapter of the [[Sutra Sthana]], it also provides an extensive ‘Table of Contents' of the entire text including an elaborate explanation of the sequence of chapters.

Isn't there one utmost factor (amongst others) for bestowing longevity, one for improving strength, one which is always to be increased, one among all happiness, one for exaltation/ecstasy and one as a path for self-realization? Yes, there are such factors. Non-violence is the utmost one to bestow longevity of living beings. Valor is the best among promoters of strength. Knowledge is the one which should always be increased. Self-control is the best factor for staying happy. Discovery/understanding/realization is the best one for feeling exalted/ecstatic. And finally, celibacy is the most effective factor in the path for self-realization, as per the view of Ayurvedic scholars. [15]

The scholar should be able to quote the lines of the text, interpret them and explain its aspects. So how should this quotation, interpretation, and explanation be done? It should be done as follows: the text of the sages, as expounded by them, should be reproduced as it is - in its full form. After thoroughly comprehending the text, one should be able to explain, elaborately and concisely, and supported by examples or anecdotes, its meaning, presumptions, reasonings, related concepts, and conclusions, in such a manner that it is comprehensible to the three types of students (above average, average and below-average).

Out of the four ''vedas'' – ''rk, yajus, sama,'' and ''atharva'' - physicians owe their loyalty to the ''Atharva Veda'' because this deals with the treatment of diseases by resorting to various practices like sacrifices, prayers, and chants, charity, moral discipline, the atonement of sins, austere practices like fasts, etc. These are advocated for treatment as well as for living a healthy, long life.

The purpose of this science is to preserve the health of the healthy and cure the disease of the unhealthy. [26]

The end of a lifespan is signaled by various abnormal changes in the sensory perception, in the objects of perception, in mind, in the intellect, and in movement. These signals help in predicting the death of an individual at a particular moment or time or day, after three days, five days, a week or ten days and after a fortnight, a month, six months or a year. ''Svabhava'' (return to the natural state), ''uparama'' of ''pravritti'' (cessation of all activities), ''marana'' (death), ''anityata'' (temporary state) ''nirodha'' (restriction in the continuation of life)- all these are synonymous with death. In the absence of such signs and symptoms, the life span is to be determined as unlimited from the prognostic point of view. In [https://en.wikipedia.org/wiki/Ayurveda Ayurveda], life span is determined by the nature of physique, constitution, and special signs. The purpose of this science is to preserve the health of the healthy and cure the disease of the unhealthy. [25-26]

[https://en.wikipedia.org/wiki/Ayurveda Ayurveda] is eternal because of the following: It has no beginning; its characteristics are self-evident, and those of things dealt with it are eternal. It has been seen that ''Ayu'' (the combination of body, its organs, mind, and soul) and intelligence about ''Ayu'' (knowledge about ''Ayu'') are perpetual. Hence ''Ayu'' and its knowledge (i.e., [https://en.wikipedia.org/wiki/Ayurveda Ayurveda]) have been eternal. The knower becomes eternal after knowing [https://en.wikipedia.org/wiki/Ayurveda Ayurveda]. Concepts such as happiness and suffering (i.e., health and illness), therapeutics and pathogens, etc. - their causes, signs, and perpetuation are all eternal. This is what is described in [https://en.wikipedia.org/wiki/Ayurveda Ayurveda]. Substances, having properties such as heaviness, lightness, cold, heat, slimy, non-slimy, etc., when combined with other substances, tend to increase by similar properties and decrease by opposite properties. For example, habitual intake of heavy food/drugs increases heaviness and decreases lightness in the body. This is similar to others too. The characteristic of these substances or phenomena is eternal. The characteristics of ''prithvi'' etc. are eternal. However, matters and their attributes are both eternal and temporary.  Theories that claim “[https://en.wikipedia.org/wiki/Ayurveda Ayurveda] came into existence after its creation” or “[https://en.wikipedia.org/wiki/Ayurveda Ayurveda] was conceived by someone and taught to his students” are false. But based on these statements, some scholars opine that [https://en.wikipedia.org/wiki/Ayurveda Ayurveda] had a beginning.

There are a few compelling similarities between ancient Greek medical literature and [https://en.wikipedia.org/wiki/Ayurveda Ayurveda].  However, ‘which school of medicine borrowed these ideas from whom?' - Has been an unresolved mystery. Some of the ideas that are significantly common to these two systems are humorism, the mechanism of blood formation, breathing, and circulation. One of the points that are widely debated in this context is the supremacy of brain versus the supremacy of heart. It looks like Hippocrates, Aristotle, Erasistratus and Galen had this confusion over the exact functions of the heart and the brain. They ascribed to the heart the functions such as perception of the sensations, motor control, intellect, emotions, etc. The above verse may be read with this background in mind. [1] Another explanation could, however, be that these vital entities are functionally dependent on the heart, though not exactly located there.

As indicated earlier in this chapter and preceding chapters, [https://en.wikipedia.org/wiki/Ayurveda Ayurveda] is that source of knowledge which teaches and deals with ''Ayu'' (life). How so? By its characteristics, it imparts knowledge of joy and suffering, benefit and harm, and authentic/authoritative and unauthentic/unreliable (sources of information). It is also that body of knowledge which informs us about long life and short life (i.e., lifespan) and substances with its properties & actions that decide a person’s longevity.

The end of a life span is signaled by the abnormal changes in the sensory perception, in the objects of perception, in mind, in the intellect, and in movement. These signals help in the prediction of the death of an individual at a particular moment or time or day, after three days, five days, a week or ten days and after a fortnight, a month, six months or a year. ''Svabhāva'' (return to the natural state), ''uparama'' of ''pravriti'' (cessation of all activities), ''maraṇa'' (death), ''anityata'' (temporary state), ''nirodha'' (restriction in the continuation of life)- all these are synonymous with death. This is at the end of life. In the absence of such signs and symptoms, the life span is to be determined as unlimited from the prognostic point of view. In [https://en.wikipedia.org/wiki/Ayurveda Ayurveda], the life span is determined by nature of the physique, constitution, and special signs. The purpose of this Science ([https://en.wikipedia.org/wiki/Ayurveda Ayurveda]) is to preserve the health of the healthy and cure the disease of the unhealthy.

Medical Education: Current medical education is disease-centric but and does not consider disease prevention as its priority. This is because of lack of understanding about what health is and how it can be preserved protected and rejuvenated. To provide complete care, a physician should be trained in both health and disease management. He should receive knowledge from authentic books and understand the practical applications of the concepts from experienced teachers before he starts taking care of people on his own.

Besides increased incidence of diseases in humans, there is increasing polarization and intolerance in our societies causing discord and violence. There is environmental degradation of the planet evidenced by global warming and increased pollution. All these phenomena imply a deteriorating health of humans, society and the planet at large. [https://en.wikipedia.org/wiki/Ayurveda Ayurveda] considers the human individual as a microcosm that reflects the health of the universe at large – the macrocosm. A healthy planet would need to have healthy societies, requiring healthy human beings. Imbalances within the bodily elements – the ''doshas, dhatus,'' etc. – lead to imbalances between the individual and his environment. This underscores the value of imbibing the knowledge about health from [[Charaka Samhita]].

There is environmental degradation of the planet evidenced by global warming and increased pollution. All these phenomena imply a deteriorating health of humans, society and the planet at large. [[Ayurveda]] considers the human individual as a microcosm that reflects the health of the universe at large – the macrocosm. A healthy planet would need to have healthy societies, requiring healthy human beings. Imbalances within the bodily elements – the ''doshas, dhatus,'' etc. – lead to imbalances between the individual and his environment. This underscores the value of imbibing the knowledge about health from [[Charak Samhita]].

Hridaya

#''Dhamanī /Dhamanyah'': A kind of blood vessel that pulsates; ''Dhamanyah'' originate in the heart and may carry different substances like ''Rasa, Rakta,'' and ''Ojas''.  

The heart; According to Suśruta, Phupphusa (left lung) and Pleeha (spleen) are situated on the left side of Hṛdaya, whereas, Yakrita (liver) and Klomia (right lung) on the right side. A few scholars suggest that the term Hridaya means ‘central’ or ‘vital’ organ, and therefore, can stand for different organs in different contexts.

Ojas

#''Ojas'': The essence of all seven ''dhatus'' that is vital for life; also suggestive of ''bala'' (immunity). The ten attributes of ''ojas'' are ''guru'' (heavy), ''sheeta'' (cold), ''mridu'' (soft), ''shlakshna'' (smooth), ''bahala'' (abundant), ''madhura'' (sweet), ''sthira'' (stable), ''prasanna'' (bright), ''picchila'' (sticky), and ''snigdha'' (unctuous). Functionally this is very closely related to ''kapha''.

#''Rasa'': The first ''dhatu'' among the seven ''dhatavah'' (or ''dhatus''). This is a liquid that is pumped out of ''hridaya'' (heart), and that circulates continuously all over the body to nourish the other ''dhatavah''. ''Vyana Vayu'' and ''Samana Vayu'' help in its circulation. The major function of ''rasa dhatu'' is ''prinana'' (nourishing).  

Rasa

#''Sira / Sirah'': A kind of blood vessel that transports the contents from one place to another; According to Vagbhata, they originate in the heart. They carry various substances including ''Rasa, Rakta,'' and ''Ojas''.  

The first Dhatu among seven Dhatavah (or dhatus). This is a liquid that is pumped out of Hridaya (Heart), and that circulates continuously all over the body to nourish the other Dhatavah. Vyana Vayu and Samana Vayu help in its circulation. The major function of Rasa Dhatu is Prinana (nourishing).  

#''Srotas / Srotamsi'': Structures meant for the transportation of ''dhatus'' that are undergoing the process of transformation. The appearance of a ''srota'' is similar to the ''dhatu'' that it transports. These are of two types: ''Sthula'' (gross), and ''Anu'' or ''Sukshma'' (minute). This term is also suggestive of a kind of vessel that facilitates the fluid exchange. Sushruta states that there are eleven pairs of ''srotamsi'' (channels) that transport eleven different biological entities: ''Prana, Anna, Udaka, Rasa, Rakta, Mamsa, Meda,'' ''Mutra, Purisha, Shukra,'' and ''Artava''.  Charak explains that there are thirteen gross ''Srotamsi'' in the body that carry the following entities: ''Prana, Anna, Udaka, Rasa, Rakta, Mamsa, Meda, Asthi, Majja, Shukra, Mutra, Purisha,'' and ''Sveda''.
