3.107

上來第二明其四人和光護法，「如是四人為護法故不名破戒」，是第三段明實不犯。

The second part above explained that the four persons harmonize their light to protect the Dharma. [The text stating,] 'Because such four persons act to protect the Dharma, they are not called breakers of the precepts,' is the third section, explaining that they do not truly commit an infraction.
