I have a friend who, at the age of 7, had an incredibly frightening experience. He was sitting on a toilet, when a strange thought occurred: "I am supported by the toilet, and the toilet is supported by the floor, and the floor is supported by the earth, but what supports the earth?" All of a sudden, his mind, confronted by this seemingly infinite regression, fell away and he found himself confronting an emptiness/void so vast that it scared the bejeebers out of him. This is the same void that Tolle fell into when he had a similarly-strange thought, "Who is it that can't stand another moment of me? There can't be two inside here. Maybe one of them isn't real."
One crazy thought is capable of bringing down the whole house of cards.
