Upanishads say, "Thou art that." I say to you: "Thou art this" -- because "that" means far away, as if God is far away. "Thou art that" -- no. "Thou art THIS": this very moment, this air that surrounds you, these chirping birds, this railway train passing by, these trees, this sun, these people, I and you, this silence where neither I am, nor you are. Thou art this. Let "this" become more important than "that" and your life will have a totally different quality to it.
