IMMORTALITY

n. state of being immortal, deathlessness, indestructibility, life which will never end; fame which will last for all time

Immortality (or eternal life) is the concept of living in physical or spiritual form for an infinite length of time. What form an unending or indefinitely-long human life would take, or whether the soul, should such a thing exist, possesses immortality, has been the subject of much speculation, fantasy, and debate, as well as a fundamental point of focus in many faiths and religions.

Immortality That which is not subject to death, deathlessness. Death is the dissolution of a compound entity, where the compound itself ceases to exist, though its elements do not perish. Nor does the ensouling entity perish because of the dissolution of its physical, astral, or other vehicle. Hence in a restricted sense certain elements can be said to be immortal, relative to the compound they form.
Theosophy teaches the constant rebirths of the identic spiritual-intellectual individuality throughout the manvantara; and that, even after union into paranirvana, the individuality, precisely because it is then on its own higher plane or sphere of life, is not lost and will reemerge at a new manvantara to pursue its own particular cycle. This eternal monad, the spiritual-intellectual individuality, is the real and truly immortal essence of the person; and within this supreme cycle of immortality are a series of less immoralities, each representing the life cycle of one of the imbodiments of the monad. Death therefore of necessity becomes a recurrent process, precisely like birth or rebirth, and of many degrees, and simply means the dissolution of some group of lower sheaths enclosing the individual in imbodiment.
Viewing the question from the consciousness aspect, death means the exchange of one mode of consciousness for others. We cannot say offhand that we are either mortal or immortal, since we contain various elements of both kinds. The essence of the individuality is unconditionally immortal, its sheaths or bodies are mortal in various and relative degrees.
