The existence of the world is always according to the perceiving organism.The mountains, the sun, the moon and stars are strictly the inhabitants of the human world. Animals with their different sense organs have a very different universe, that is animal universe. Every event in the external world is dependent on the observer for its happening. For example : a rainbow; if the sun is shining and there is a person standing, if there is moisture in the atmosphere there would be a rainbow. There is no rainbow if no one is watching it. Similarly this is applicable to the mountains, rocks, rivers, fire everything. All existence is a relationship. None of these things constitute existence until related with the neurological complex. Now we can say that the neurological complex belongs to the same world as the Sun, it’s a physical pattern, physical behavior, physical energy. It takes this much complexity of pattern to evoke the world. The world and oneself are the two phases of a single process. This whole existence is like a fabric which cannot be divided into different threads. There is no mind over matter or matter over mind, it is existence as a whole.
