When considering these five appetites, which are the deepest man has, one finds that all the efforts man makes to satisfy them seem to be in vain. They can only be satisfied by spiritual attainment; that is the only answer to them. Thus the desire to live can only be satisfied when the soul realizes its eternal life. For mortality exists in conception rather than in reality. From a spiritual point of view mortality is the lack of the soul's understanding of its own self. It is like a person who had lived all his life in the conception that his coat was himself, and when that coat was torn from him he believed that he would die. One experiences the same in life. The soul gets from this physical body a kind of illusion and identifies itself with this mortal being; wise people of all times have practiced meditations to give the soul a chance to realize its independence of the physical body. Once the soul has begun to feel itself, its own life, independently of its outer garb, it begins to have confidence in life and is no longer afraid of what is called death. As soon as this phenomenon takes place a person no longer calls death "death"; he calls death a change.
