There is no other reason but one, and that is total emptiness. Whosoever is empty is whole. Emptiness is the foundation of wholeness. Rightly said, emptiness alone is whole. Can you draw a half emptiness? Even geometry cannot draw a half zero; there is no such thing as a half zero. Zero or emptiness is always complete, whole. Part-emptiness has no meaning whatsoever. How can you divide emptiness? And how can it be called emptiness if it is divided into parts?
Emptiness is irreducible, indivisible. And where division begins, numbers begin; therefore, number one follows zero. One, two and three belong to the world of numbers. And all numbers arise from zero and end in zero. Zero or emptiness alone is whole. He is whole who is empty. And it is significant that Krishna is called whole, because this man is absolutely empty. And only he who is choiceless can be empty.
