Eckhart Tolle - You are the universe, expressing itself as a human...
You are the universe, expressing itself as a human for a little while.
This quote is pieced together from a discussion with Oprah in the video below starting around 1 hour, 25 minutes. Tolle and Oprah essentially create this quote together, but it is legitimate to claim this as a Tolle quote.
Tolle also says a nearly identical phrase about a minute before: "You are this universe experiencing itself, very briefly, as a human."
