No one can know the origin of anything. For example, there is a green gram seed. Who can trace its genealogy? But one can recognise its future. The moment it is placed in the mouth and munched, that will be its end. Its origin is not known, but its end is in our hands. This is the reason why man is enjoined to concern himself about his end. Do not worry about rebirth because that is not in your power. Strive only to ensure that your end is pure and sacred. That calls for sadhana (spiritual practice). Many imagine that the quest for God is sadhana. There is no need to search for God. When God is all-pervading, inside and outside, where is the need to search for Him? The only sadhana one has to practice is to get rid of the Anatma bhava (identification of the self with the body). Anatma is that which is impermanent. When you give up the impermanent, you realise what is permanent and eternal. – Divine Discourse, Jan 14, 1993
