4.108

論。所謂推求至之與心　釋曰。下釋有二。先總舉。後別名。此初也。上言顯示從生滅門。入真如門云何顯示。故即釋云。推五蘊等。然此五陰不過色心。色蘊名色。餘四名心。推此色心。離心無性。既生滅法總即色心。故知生滅即真如也。

[Treatise:] That is to say, examining [... and mind].
[Commentary:] The following explanation has two parts: first, a general formulation; second, specific designation. This is the first. Above, it was said that this reveals the entrance into the gate of tathatā from the gate of arising and ceasing. How does it reveal it? Hence it immediately explains: examining the five aggregates and so forth. Now, these five aggregates are nothing other than form and mind. The aggregate of form is called form; the remaining four are called mind. Examining this form and mind, apart from the mind they have no intrinsic nature. Since the phenomena of arising and ceasing are, in aggregate, simply form and mind, one thereby knows that arising and ceasing are themselves tathatā.
