Death is separation of the soul from the physical body. Death becomes the starting point of a new life. Death merely opens the door to a higher and fuller form of life. Birth and death are jugglery of maya. He who is born begins to die. He who dies begins to live. Life is death and death is life. No one comes, no one goes. Brahmn or the eternal alone exists.
Just as you move from one house to another, the soul passes from one body to another to gain experience. Just as a man casting off worn-out garments takes new ones, so the dweller in this body, casting off worn out bodies, enters into others which are new.

Life is a continuum. Death is necessary for further evolution. Dissolution of the body is no more than sleep. Birth is like waking up. Death brings new life. A man of discrimination is not afraid of death. Death unlocks the door to a wider existence. The soul is a circle whose circumference is nowhere but its centre is in the body. Death means the change of this centre from one body to another.

The supreme soul or Paramaatmaa is deathless, decay less, timeless, causeless and space less. It is the source and substratum for body, mind and world. There is death for the physical body, a compound of five elements. The eternal soul is beyond time, space and causation.

To free yourself from birth and death, you must become body-less. Body is the result of karmas or actions. If you free yourself from Raag-Dwesh, or likes and dislikes, you will be free from karma. If you annihilate ignorance through knowledge of the imperishable, you can annihilate the ego. The root cause for this body is ignorance. He who realizes the eternal soul, which is formless and attribute less, infinite and unchanging, frees himself from death.

The individual souls or Jeev build various bodies to display their activities and gain experience from this world. They enter the bodies and leave them. The process goes on. This is known as transmigration of souls. The entrance of a soul into a body is called birth. The soul’s departure from the body is death.

Man has always tried to know what happens after the death of an individual. Science has been struggling to unravel the mystery of what lies beyond death. Experiments have yielded many interesting facts. Natural death, it is said, is unknown to unicellular organization. When life on earth consisted of these creatures, death was unknown. The phenomenon appeared only when from unicellular the multi-cellular evolved.

Laboratory experiments have shown that whole organs such as thyroid glands, the ovary, suprarenal gland, the spleen, heart and kidneys isolated from the body of a cat or a fowl, can be kept alive in vitro to show increase in size or weight due to the appearance of new cells or tissues.
