What was conceived has grown physically, and some of the expressions of this knowledge "I Am" have achieved tremendous things. Some have became avatars, some have achieved success in various fields. At the end of the time span the magnificent personalities, and whatever they have achieved - both have disappeared. It may have been for many years; this "I Amness" may have remained existent for hundreds of years in particular cases; still, however long the time, there is an end to it.
Some of these avatars and jnanis have understood what the "I Amness" is, that it needs a body before it can manifest itself, and the body can only come out of sexual intercourse. Having understood it, instead of remaining in that knowledge apart from manifestation, and merely observing manifestation, they started giving advice to that which is only conceptual; all manifestation is conceptual. They said, "Let there not be sexual relations." Many of these avatars and jnanis have given this advice. Has it happened? Has the rain stopped? Has the production of population stopped? No. Nature will take its course. It is only to be understood, nothing is to be done..
