It seems to me that thought often gets a bad wrap in non-duality because of its role in the apparent creation of duality. It is also blamed or pointed out for luring one out of the present moment (so to speak)into the conceptual world. New Age teachings are often condemmed for their role in advocating the manipulation of thought to achieve a better life. The Advaita perspective is to dismiss thought and treat it as just another phenomena that arises in Awareness and many teachers emphasize how thought is the tool of the ego to keep the search going. The role that thought plays in our "lives" really eluded me up for a long time. What I have come to experientially understand is that once we get a glimpse of our true nature, thought ceases to be the slave of ego and becomes infused with our true nature;thoughts become life affirming instead of condemming. Knowing your true nature is not freedom from thought or your ego, but a holistic experience of our true nature which incorporates thought.
