Consciousness is a singular for which there is no plural.

Whence come I and whither go I? That is the great unfathomable question. Science has no answer to it.

Quantum physics thus reveals a basic oneness of the universe.

We do not belong to this material world that science constructs for us. We are not in it; we are outside. We are only spectators. The reason why we believe that we are in it, that we belong to the picture, is that our bodies are in the picture. Our bodies belong to it. Not only my own body, but those of my friends, also of my dog and cat and horse, and of all the other people and animals. And this is my only means of communicating with them.
