Non-Dual Teachings point directly to the truth that in reality there is only one undivided consciousness appearing as everything.  The ego, or sense of being the separate individual that we appear to be, is revealed as an appearance which is an aspect of our experience but is not our true self.  Non-dual teachings emphasize that the truth that we seek is the very one who is seeking for it, and this can be realized right now since the truth is already what we are rather than something we will one day become through our efforts.  Living in India until 1950, one of the most beloved non-dual teachers is Ramana Maharshi whose silent presence is his essential teaching. When pressed to share his wisdom in words for those who could not receive it in silence, he offered instruction in the direct path of Self-Inquiry which directs the seeker of truth to the perennial question "Who Am I?".  Advaita Vedanta, Zen, and Dzogchen are examples of non-dual teachings from India, Japan, and Tibet.
