瑜伽論記 3.48

3.48

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.
