The anatomy of death.

Medical science does not treat death as an independent physiological phenomenon. It believes that disease is the cause of death and treats both as preventable phenomena. Doctors and relatives nurture a guilt complex when death occurs. The moment of natural death is robbed of its poignancy. There is no cause of death. Death of the physical body is an intrinsic, time governed, built-in ontolytic program. It completes the biologic trajectory of the individual organism which begins at conception and ends with death. In this article, the actual built-in mechanism and operation of the physiological process of death is suggested vis-a-vis biology and medicine. The physical body of an individual is like a biological gadget which is constantly charged with life force received from cosmic energy through the subtle body which is an implement that cannot be objectified in the same way as the gross physical body but is experienced only subjectively by one and all, as mind (antahkaran in Sanskrit and Indian languages, meaning inner instrument, a subtler instrument in contrast to external organs of actions like limbs, tongue, etc. of the physical body). This life force keeps the subtle body and the entire physical body live and functioning. It maintains the body's integrity and internal homeostasis throughout life. The physical body like a gadget has a built-in program which decides how much total capacity, pace and quantum of life force it can use. It is often referred to as breath quota and heartbeat quota, however, they are manifestations and not the mechanism and operation of life and death in the physical body. When the quantum of life force of the physical body is exhausted, the subtle body, a connector for life forces departs, leaving behind the physical body. The vital functions stop and the person is declared dead. It is usually referred to as departure of soul (Pran or Jiva in India) from the physical body in common parlance. This phenomenon of predetermined capacity, pace and fixed quota of life force is operational in all the components of the body. Each cell, each organ, each system and the whole body is a packed unit of bioenergy. They are in structural and functional dynamic homeostasis under constant flux resulting in constant change in the body. The rate of expenditure contributes towards deciding the total life span of the cell, organ, systems and individual. It accounts for the phenomena of cell death, progressive diminution in vitality, change in organ and system functions during life and physical death of an individual at the end. Death is a bio-cosmic phenomenon governed by biological laws. There is variation in life span at the interspecies and intraspecies levels because we measure lifespan of an individual in terms of physical time and not in terms of biological time which is an independent entity, not measurable and predictable as physical time. Everyone lives one full unit of life in terms of biological time which begins at conception and ends with death. The normal distribution of each biological feature, including the biological unit of life, is independent of one another making each individual unique. The biological clock runs at its own dynamic unique pace in every individual. The biological timer starts ticking at conception and stops when the life force quantum is over. When the person dies, the physical body stops functioning and is left behind for others to dispose of. The timing of death is beyond the realm of objective perception and cannot be equated with chronological or physical time. It is a trans-science and trans-technique phenomenon beyond the ken of humankind to alter its mechanism and operation. The article explains the impact of extrinsic and intrinsic diseases, various treatments such as organ transplant, as well as the impact of lifestyle on the biological time scale of an individual. It spells out the difference between natural and unnatural death. With this understanding, death can be appreciated, accepted and respected as a built-in operational intrinsic physiological phenomenon for the end of one's life. It is a must for the survival and healthy continuity of all the species in the biological world including mankind.
