In the following video David Lynch describes consciousness. He says, "if you have a golf-ball sized consciousness then when you read a book you will have a golf-ball sized understanding. If you could expand that consciousness, then when you read the book you will have more understanding. It's consciousness. And there is an ocean of pure, vibrant consciousness inside each one of us and it's right at the source of thought. Transcendental Meditation is a simple and easy, effortless technique that allows any human being to dive within, experiencing subtler levels of mind and intellect, transcending to experience this ocean of pure consciousness."
Another quote from David Lynch from his book 'Catching the Big Fish':
"You've got hundreds of rooms. And in those rooms, there's a lot of junk... Now you take this elevator, which is going to be the dive within. And you go down below the building; you go to the Unified Field beneath the building - pure consciousness. And it's like electric gold. And that electric gold activates these little cleaning robots. You're on the road to a beautiful state of enlightenment."
