For instance, I once had an opportunity to study with the great Tibetan lama Dilgo Khyentse Rinpoche in Nepal. Before making the trip, I had a dream in which he seemed to give me teachings about the nature of the mind. This dream struck me as interesting for two reasons: (1) The teachings I received were novel, useful, and convergent with what I later understood to be true; and (2) I had never met Khyentse Rinpoche, nor was I aware of having seen a photograph of him. This preceded my access to the Internet by at least five years, so the belief that I had never seen his picture was more plausible than it would be now. I also recall that I had no easy way of finding a picture of him for the sake of comparison. But because I was about to meet the man himself, it seemed that I would be able to confirm whether it had really been him in my dream.
First, the teachings: The lama in my dream began by asking who I was. I responded by telling him my name. Apparently, this wasn’t the answer he was looking for.
“Who are you?” he said again. He was now staring fixedly into my eyes and pointing at my face with an outstretched finger. I did not know what to say.
“Who are you?” he said again, continuing to point.
“Who are you?” he said a final time, but here he suddenly shifted his gaze and pointing finger, as though he were now addressing someone just to my left. The effect was quite startling, because I knew (insofar as one can be said to know anything in a dream) that we were alone. The lama was obviously pointing to someone who wasn’t there, and I suddenly noticed what I would later come to consider an important truth about the nature of the mind: Subjectively speaking, there is only consciousness and its contents; there is no inner self who is conscious. The feeling of being the experiencer of your experience, rather than identical to the totality of experience, is an illusion. The lama in my dream seemed to dissect this very feeling of being a self and, for a brief moment, removed it from my mind. I awoke convinced that I had glimpsed something quite profound.
On the other hand, he concludes with:
My travels in spiritual circles had also brought me into contact with many people who seemed all too eager to deceive themselves about experiences of this kind, and I did not wish to emulate them. Given these considerations, I did not believe that Khyentse Rinpoche had really appeared in my dream. And I certainly would never have been tempted to use this experience as conclusive proof of the supernatural.
