大乘起信論略述 2.177

2.177

[Treatise:] How does one cultivate ... falsely give rise to ... transgression. [Exposition:] Here the marks of the three kinds of discipline are clarified. What is termed "not stealing," etc., clarifies the discipline of ethical restraint (saṃvara-śīla) based on laypersons, because it checks laypersons from committing much evil. "If one is a renunciant," etc., clarifies the discipline of gathering wholesome phenomena (kuśaladharma-saṃgrāhaka-śīla) based on renunciants, because they have already departed from evils and are exhorted to advance in the wholesome. From "one should guard" onward, it also clarifies the discipline of benefiting sentient beings (sattvārthakriyā-śīla) based on renunciants, because preventing others from doing evil is compassionate protection.
