大乘義章 13.23

13.23

淨望味定亦三句說：一具緣多少。示除因緣，有餘三種。從淨生染，非自分故，無其因緣；餘三寬故，所以得有。二就地分別。望自地味得具三緣，望下亦然。謂退轉時生下味故，有次第緣及增上緣。他界緣使緣上而起，故有緣緣。望上地味無次第緣、緣緣之義，但增上緣。何故望上無次第緣？上地味定愛著自地，心從上地有漏心生，故下淨定不得與上為次第緣。何故望上無其緣緣？一切煩惱緣於自地及上地生，不緣下故。何故望上有增上緣？雖無意根親生增上，萬法不障，增上緣寬故得有之。三品數分別。於為緣處，不分上中下品差別（此淨定竟）。

Pure [concentration] viewed in relation to tainted concentration is also explained in three clauses: First, the completeness and number of conditions. Excluding the cause-condition, there are the remaining three kinds. Arising from pure to defiled is not of the same category, so it lacks its cause-condition; because the remaining three are broad, they are therefore able to exist. Second, discrimination with respect to stages. Viewed in relation to the tainted [concentration] of its own stage, it can possess the three conditions; viewed in relation to lower ones, it is also likewise. This means that when regressing, it generates lower taintedness, and therefore has the immediate condition and sovereign condition. Because the proclivities that take other realms as objects arise by taking higher [stages] as an object, there is the object-condition. Viewed in relation to the tainted [concentration] of higher stages, there is no sense of an immediate condition or an object-condition, but only a sovereign condition. Why is there no immediate condition viewed in relation to higher ones? Higher-stage tainted concentration is attached to its own stage, and its mind arises from a higher-stage sāsrava mind; therefore a lower pure concentration cannot serve as an immediate condition for a higher one. Why is there no object-condition viewed in relation to higher ones? All afflictions arise by taking their own stage and higher stages as objects, not by taking lower ones. Why is there a sovereign condition viewed in relation to higher ones? Although it lacks the proximate generating sovereignty of the mind-faculty, all dharmas do not obstruct; because the sovereign condition is broad, it can therefore exist. Third, discrimination by grades of quality. Regarding the places where it serves as a condition, no distinction of superior, medium, and inferior grades is made (this [treatment of] pure concentration is concluded).
