味望淨定，亦三句說：一具緣多少。除其因緣，有餘三種。二就地分別。於自地中具足三緣，望下亦爾。上味心後起下淨定，防自地退，故望下淨有其次第、增上緣義。依下淨定學觀上味為苦集觀，故上地味為下緣緣。望上淨定得有緣緣、增上緣義，是義云何？他人上淨，緣我下味生厭惡心，故有緣緣；我味不障他人上淨，故有增上。三品數分別。於為緣處，不分上中下品差別（此兩門竟）。

Tainted with respect to pure samādhi is also explained in three points: First, the number of conditions it possesses. Excluding the cause condition, it possesses the remaining three kinds. Second, distinction by stage. Within its own stage it fully possesses three conditions, and with respect to lower [stages] it is likewise. After a higher tainted mind, a lower pure samādhi arises to guard against retrogression from its own stage; therefore, with respect to lower pure [samādhi], it has the meaning of the immediate and dominant conditions. Based on lower pure samādhi, one trains in contemplating higher tainted [states] as the contemplation of suffering and its origin; therefore, higher-stage tainted [states] serve as the object condition for lower [stages]. With respect to higher pure samādhi, it can have the meaning of the object condition and dominant condition. What is the meaning of this? Another person's higher pure [state] takes my lower tainted [state] as an object to give rise to a mind of aversion, and therefore there is an object condition; my tainted [state] does not obstruct another person's higher pure [state], and therefore there is a dominant condition. Third, distinction by grades. Where it serves as a condition, there is no distinction among superior, middling, and inferior grades (this concludes these two sections).
