On matter, spirit, and transmigration of the soul...

There is no endurance of the changing body. That the body is changing every moment by the actions and reactions of the different cells is admitted by modern medical science; and thus growth and old age are taking place in the body. But the spirit soul exists permanently, remaining the same despite all changes of the body and the mind. That is the difference between matter and spirit.

This individual soul finally leaves the body at death and transmigrates to another body… The living being is eternal by nature, but due to his bondage in the material existence he has to change his body from one to another. This process is called transmigration of the soul.
