6.402

述曰：論主答曰：相、用別者，別立為善。餘所翻善相、用不別，故不立之，汝何須責？問：若爾，此何別自？餘何無用？

The Commentary states: The author of the treatise answers: Those whose marks and functions are distinct are separately established as wholesome. The other inverted wholesome factors do not have distinct marks and functions, and therefore are not established; why must you raise this objection? Question: If so, why do these have a distinct nature, while the others lack such function?
