Then came the explosion. Now, scientists also talk about this explosion; they call it the Big Bang. Then everything exploded. The nothingness disappeared and things appeared. It is still a hypothesis, even for scientists, because nobody can go back. For scientists it is a hypothesis, the most probable hypothesis at the most.

There are many theories proposed, propounded, but the Big Bang theory is generally accepted - that out of that nothingness things exploded like a seed explodes, becomes a tree. And in the tree then millions of seeds; and then they explode. A single seed can fill the whole earth with greenery. This is what explosion means.

Have you observed the fact of this mystery, that a small seed, barely visible, can explode and fill the whole earth with forests? Not only the whole earth: all the earths possible in existence. A single seed! And if you break the seed what will you find inside it? Just nothingness, just pure nothing. Out of this nothingness, the whole has evolved.

For scientists it is just a hypothesis, an inference. For a buddha it is not a hypothesis, it is his experience. He has known this happening within himself. I will try to explain it to you, how one comes to know this beginningless beginning because you cannot go back, but there is a way to go on moving ahead. And, just as everything moves in a circle, time also moves in a circle.
