"Eckhart teaches to go beyond thought." Is correct, but it's also just a thought to be watched.
Subtle recursive comment, HYKG. But not, in my experience quite right. The "going beyond thought" is an experience, not a thought or concept. Eating your first orange was not a thought. Eckhart introduces a lot of concepts, and, until they are experienced, they are all concepts. He's a little weaker on the sadhanas, or spiritual practices, and then came out with some CDs with some exercises. The personality we call Eckhart Tolle is very cerebral, and accompanies that with a very light verbal touch which gives his words great power. But his focus is cerebral.
His CD set "Gateways to NOW" offers some simple techniques to releasing the grip of the mind. The place "beyond thought" is the fundamental Source of both thought and form, and it is who/what we are. In his latest reminder he recalls that we are not "in the now," but that we are the now. Very depersonalizing until you rest there or return there often enough to recognize it as "home," "Self" and eternity...not a thought to be watched.
