俱舍論疏 16.92

16.92

[On the passage] from "The Śāstra says" up to "because they are mutually associated": this clarifies that the prayoga, maula, and pṛṣṭha of wholesome karmapathas all arise from the three wholesome roots, because they are all originated by a wholesome mind. Because they are originated from the causal mind, they are called wholesome; and because a wholesome mind is associated with the three wholesome roots, all wholesome karmapathas therefore arise from the three roots.
