3.48

戒自性中，以三業為性故言身語業等，如唯識說：受菩薩戒故通三業。依處通情非情者，性戒遮戒，隨其所應通依二故。修性自性謂三摩地者，其四無量慈體，無瞋悲體，不害善體，不嫉捨，則三善根善捨數也，今從所依故定為體。

Within the self-nature of morality, taking the three karmas as its nature is why it speaks of "physical and vocal karma, etc."; as the *Triṃśikā* says, because one receives the bodhisattva precepts, it extends to all three karmas. That the basis extends to the sentient and insentient is because, as appropriate, both natural precepts and instituted precepts extend their basis to both. Regarding "the self-nature of cultivation refers to samādhi": the substance of the four immeasurables—loving-kindness is non-hatred, compassion is non-harming, sympathetic joy is non-jealousy, and equanimity is the wholesome mental factor of equanimity among the three wholesome roots; here, following that upon which they depend, meditative concentration is taken as their substance.
