次、明漏、無漏：若依《毘曇》判此十禪，皆名有漏；緣諦智修，名無漏禪。不爾，但緣事修，名有漏禪。《成論》亦爾，根本等是有漏；空無相心修，名無漏。

Next, explaining tainted and untainted: If judged according to the Abhidharma, these ten dhyānas are all called tainted; cultivated by wisdom focused on the truths, they are called untainted dhyāna. Otherwise, cultivated merely with a focus on phenomena, they are called tainted dhyāna. The Tattvasiddhi is also like this: the fundamental and others are tainted; cultivated with an empty and signless mind, they are called untainted.
