Fabricated, dependent and perfected: So the wise understand, in depth, the three natures. What appears is the dependent. How it appears is the fabricated. Because of being dependent on conditions. Because of being only fabrication. The eternal non-existence of the appearance as it is appears: That is known to be the perfected nature, because of being always the same. What appears there? The unreal fabrication. How does it appear? As a dual self. What is its non-existence? That by which the non-dual reality is there.
