This chapter explicates the signs and symptoms of imminent death due to diminution of Agni (factor responsible for digestion and metabolism). The components of life like lifespan, strength, complexion, enthusiasm, health, growth, luster, and immunity are dependent upon the status of agni. Diminution of its power causes generalized symptoms indicative of imminent death. Declaration of the estimated time for death might be based on experience of many experts of that time, which can now be reestablished in light of present scientific developments. The clinical signs and symptoms given in this chapter are useful as an additional information for assessment of prognosis.
Keywords: Anujyoti, Arishta, Bali,Agni, digestion.
The present chapter deals with near death signs that arise due to decrease in digestive capacity of a person i.e. jatharagni. The chapter indicates importance of digestive and metabolic functions of agni. The ingested food is helpful and nutritive to body only if, it passes through various digestive and metabolic processes successfully. This food nourishes the body at cellular level and it reflects in the form of good complexion, strength, good health, enthusiasm, and nourishment to formation of ojas. Some part of food digested with the help of agni nourishes sensory organs along with mana (mind) too. Ayurveda has emphasized the importance of quality and quantity of Agni for metabolic activity of the body, that if the agni works well, the person lives long and if it ceases; the person is going to die.[ Charak Samhita Chikitsa Sthana 15/4]
Some signs seen in diseased or in healthy person, with or without any significant/visible pathology leading to death, are mentioned. These signs occurs due to initiation of some life threatening disease with poor prognosis even in initial stage.
It is emphasized that any extreme alternation in body physiology or psychology, person’s own behavior, mental functions, etc. without any significant reason; is also one of the sign for death.
Mind supremacy is also highlighted, as the mental strength of a person declines due to advancement of disease; then the person is likely to die. Composition of physical body (sharira), sensoria (indriya), mind (sattva) and soul (atma) is called life (ayu). With advanced stage of disease, physical body gets damaged, sensoria may also get affected and soul becomes ready to leave the diseased body; in such situation only strong mind power can sustain life as physical body follows mind and vice versa.[ Charak Samhita Sharia Sthana 1/155]
It is elucidated that if person’s life span has ended; even good quality of physician, medicine or care taker are helpless. In a nutshell person’s life span is fixed and when it is gets finished, some signs are manifested called arishta.
Further, status of dying person is described briefly that, he may develop aversion to all loving and respectful persons, friends, food (and other basic essentials for surviving) etc. as his soul is almost in position to detach this body and preparing self to travel to other world. The chapter defines arishta with a new dimension. The concomitant aggravation of dosha (either qualitative or quantitative) with life-threatening diminution of dhatu is significant in the prediction of death.

The physician should always assess the prognostic signs of life in diseased as well as in healthy person. Because the knowledge of prognostic signs of life and diseases helps to decide remaining lifespan and hence treatment can be planned accordingly.

Here is the re capitulatory verse: The signs originated due to extensively vitiated and pervaded dosha throughout the body, and already transcended the stage of the treatment are called arishta (signs of death). 
Tattva Vimarsha (Fundamental Principles)
- Optimum quality and quantity of agni is necessary for sustenance of life.
- Stable mental status, complexion and mental strength are markers to predict lifespan of patient.
- Sudden changes in likings, gentleness, memory, sacrifices, intellect and strength in a person are pre-indications of death.
- Altered sensorium and psychological status leading to various delusions and hallucinations are pre-indicators of death.
- Near the end of life there is general decline in complexion, voice, agni, speech and state of mind, as well as sleep pattern alters.
- The prognostic signs of life in diseased as well as in healthy person shall always be assessed. This helps to decide remaining lifespan and planning treatment.
- The signs originated due to extensively vitiated and pervaded dosha throughout the body, and already transcended the stage of the treatment are called arishta (signs of death).
Vidhi Vimarsha (Applied Inferences )
Metabolic process and thermoregulatory center situated in hypothalamus play key role to generate and maintain body temperature respectively. Reduced temperature shows slow metabolic process and gradually it ceases completely, causing death. With the help of healthy digestive power and proper metabolic activity; food nourishes the body and provide macro and micronutrients to the body.[ Charak Samhita Chikitsa Sthana 15/3]
In any manner, hampered blood or oxygen supply to the brain leads to lack of concentration, weakness of mental functions or agitation. Deposition of any toxic substance or progressive degenerative changes of mind also leads to such symptoms. Ageing and death are considered as natural process with passage of time.[ Charak Samhita Sharira Sthana 4/36] With declining phase of life, ageing symptoms start to appear, as new cell production is almost stops and older cell destruction continues. With the passage of senescence; weakness, decreasing appetite, muscular wasting, decreased fluid intake, neurological dysfunctions, decreasing level of consciousness etc. are common symptoms manifest and gradually leads to cessation of life.
Every individual has good appetite and capability of digesting foods he regularly ingests. Ksheerada(only on milk), ksheera-anna(milk and rice products), annada (staple foods), are three basic stages of life. During ageing process, gradual reduction in both qualitative consumption and digestive abilities are observed. This in turn influences the individual’s physical and mental wellbeing leading to reduction in life span ending in death.
As per the principle of Yatha Brahmande Tatha Pinde, whatever is there in the universe, is there in the human body. Hence there should be some connections between human body and the universe. When the soul is preparing for detachment from the body to start its journey to other world, there should be some indications from the universe as indicator of impending death. As per Indian tradition, offerings of food to birds specially to crow and non-acceptance of offering by crow may indicate the preparation of soul for detachment from living body. Inability to see Arundhati in the sky is another indication of the same. [4 – 5]
Acute loss or gain of luster or body weight can be the result of carcinogenic condition or severe catabolic changes taking place in the body that can be fatal for the person. 
Brain regulates multiple functions related to sensory, motor and autonomous nervous system like emotions, intellect and many other activities. Amygdala, and physiological functioning of limbic system of brain, are responsible for proper emotions and its expression. If these are deviated grossly, it shows involvement of higher center in pathogenesis and poor prognosis.
Gradual cessation of the functions is a clear indication of either degenerative changes or space occupying lesion (SOL) in the specific area. Acute toxicity of brain also leads to acute degeneration of brain cells or infarction that leads to hampering of function. 
Sudden appearance of crescent shaped streaks or blood vessel network on forehead may relate with Amyloidosis. It is a rare disease that occurs when a protein (albumoid) substance gets deposited in person’s organ. This abnormal protein is usually produced in bone marrow and can be deposited in any tissue or organ. The prognosis is poor. [8-9]
If person having combination of dual type of activity of mind i.e. exaggerated (in form of tremor), and diminished activity (in form of stupor), simultaneously; is supposed to die within a month. These dual types of signs may indicate increased intracranial pressure (ICP) due to localized mass like hematoma, neoplasm, abscess, edema, infarction, obstruction in CSF circulation, diffuse brain edema (like encephalitis, meningitis, or diffuse head injury), thrombosis, or idiopathic intracranial hypertension.
Symptoms of raised ICP are altered mental state, lethargy, irritability, slow decision making and abnormal social behavior. Ultimate result of the patho-physiology of such condition is stupor, coma and death. Rapidly rising ICP leads to syncope, seizures. These neurologic changes seen in increased ICP are mostly due to hypoxia and hyper apnea. 
If fecal matter or other excreta are mixed with ama, it sinks straight in water due to its heaviness. Same concept is applied to other body discharge or dhatus too. Fecal matter is the end product of digestion. Hence, if it sinks in water it shows incomplete or improper digestion of food. Shukra is the last dhatu and hence all dhatvagni contribute (directly or indirectly) in its formation. To sink shukra in water is indicative that the dhatu is in sama stage. To get dipped all the three i.e. feces, urine and semen shows impairment of jatharagni along with dhatvagni functions leading to qualitative mal-formation of all dhatus. Such situation has been considered as fatal. 
Muscular wasting of hands and feet is a type of neurogenic muscular atrophy with poor prognosis.
Swelling over both extremities along with face is an indication of damage of two vital organ simultaneously i.e. heart and kidney and hence survival of patient is difficult.
Appearance of blue lines occurs in various conditions. This may be indication of venous congestion due to heart, lungs and liver diseases, requiring attention while scaling the span of life. 
Immediate disappearance of manifested small pox subsequently develops acute toxemia and hence leads to death. 
Combined manifestation of stiff neck along with inflamed throat and scrotum and swollen tongue is the condition of tertiary stage of syphilis when the person develops syphilitic meningitis (complication of untreated syphilis), is a life threatening condition. 
Visual (or even other sensorial) hallucinations are often part of the dying experience. Person may unknowingly involve in such activities with such illusions. This is the phase when the soul is getting ready to detach from the body and to travel for another world. The dying may turn their focus to “another world”, and thus may see (or feel other sensorial hallucination of) some unusual things, he may see or talk to such people who are already died. [18-19]
Various kinds of hallucinations are indications of altered psychological state of dying person, and to have laughter without any specific cause is also result of such hallucinations. To lick own lips is the sign of dehydration and coldness of breath and extremity are the indication of almost reducing function of heart and hence, stoppage of blood flow to concerned area.  Delusions along with altered sensorial organ is the sign of death. 
Days or hours before death, the dying person becomes less and less responsive to voice and touch and may not awaken. (Sometimes, quite unexpectedly, the person may appear well and even look as if he/she is going to recover. The person may be alert and talkative. But it does not mean that he is getting well; of course the time may be used as a “window of opportunity” to say what you need to say and have closure).  These all of sudden recovery changes are also signs of near death. 
As per ancient classical texts, life span of everyone is fixed and pre-ordained. No one can add years to the life only quality of life can be improved with medications. The same thing is meant here when it is said that death is the destiny of patient and that desirable quality of medicine, human resource and all other things cannot make the person outlive his destined lifespan.
