The truth is a big truth, very big. It is big like the sky. It is true. Fire burns—true. There is one truth, even on the relative level; it is just reflected in different ways. It is like the story of the ten blind men and the elephant. One blind man says the elephant is like a tree trunk, one says it is like a leaf, and so on, but really it is just one elephant. Likewise, truth is not relative truth, but it is one truth, which includes different discoveries.
