Thrangu Rinpoche writes:
Although the essence of Mahamudra is non-existent, at the same time its manifestation is completely unobstructed. For instance, we can say our mind is empty because when we look for it, it is nowhere to be found. However, when we don’t look, it manifests everything. It is completely unobstructed in its nature.
What does this mean? How is the mind completely unobstructed?
“The essence of Mahamudra is non-existent” is the realization of the emptiness of phenomena. All phenomena are empty of existence, empty of self, and so they leave no trace. The minds nature is to manifest. When there is a preference towards emptiness mind’s manifestation is a problem—something to be overcome. This is the subtle reference point of emptiness as self. Reality is as it is—the need to control is extra. There isn’t a problem.
I found this inquiry extremely useful. When I ran across Thrangu Rinpoche’s quote, I felt like he was pointing to the non-dual in a profound way that seemed somewhat mysterious to me. The emptiness part didn’t so much, as lately there has been a continual access to the recognition of emptiness, but the statement about the mind being completely unobstructed was puzzling. Going into the question revealed new depths of identification and holding, especially with regards to being the empty or causal self.
