Ramana's words, "Who am I?" paragraph 6 "Nor is there any such thing as the physical world apart from and independent of thought.

In deep sleep there are no thoughts: nor is there a world. Just as the spider draws out the thread of the cobweb from within itself and withdraws it again into itself, in the same way the mind projects the world out of itself and absorbs it into itself."
