6.359

上來第一明罪體相，下教觀入滅除王罪，還就向前三番教之：一就上有門明有殺罪，生王愧心，令王作其慚愧非有；二「色無常」下就前破有入空門中教王觀入，令王作其空見非有；三「殺無常」下就前破空顯實門中教王觀入，令王作其常見非有。

The above was the first [part], explaining the substance and marks of guilt. Below, it teaches contemplation and entry to eradicate the king's guilt, again teaching it in terms of the previous three turns: first, in terms of the gate of existence above, it clarifies that the guilt of killing exists, giving rise to the king's remorseful mind and causing the king to produce the non-existence of shame and remorse; second, from "Form is impermanent" downward, in terms of the previous gate of breaking through existence to enter emptiness, it teaches the king to contemplate and enter, causing the king to produce the non-existence of the view of emptiness; third, from "Killing impermanence" downward, in terms of the previous gate of breaking through emptiness to reveal reality, it teaches the king to contemplate and enter, causing the king to produce the non-existence of the view of permanence.
