The theory of transmigration of souls emphasizes the continuity of the soul. Worldly existence is a stage of transition from past existence towards future lives. Life is a continuous process. Birth and death are simply landmarks. When a birth or death takes place there is merely a shift in the man`s position. The soul discards damaged physical bodies and assumes new forms. This belief is the base of Hindu social and metaphysical thought.

According to the Indian Puranas, it is rare for a jiva to be born into a human body. Reincarnation occurs when the soul, comes back to life in a new body after the death of a body.
Transmigration of souls is called metempsychosis is based on the theory that a soul may pass out of one body and reside in another. This theory is most spoken of in Hinduism and was developed in the Upanishads. Souls are regarded as a release of the divine spirit. The theory of transmigration of souls has been closely interwoven with the concept of Karma. This cycle of karma and transmigration of souls may extend through innumerable lives. The ultimate goal is the re absorption of the soul into the ocean of divinity. Transmigration of soul occurs when it reaches the perfect state of the almighty. The soul goes through several lives for attaining perfection.

They reach the sun after some complications and then in the flashes of lightning they are led to the world of Brahman. The souls of the moral dead who are unaware of the mystery as well as perform sacrifice, almsgiving and penance, go through similar process and find their way to heaven.
