摩訶止觀 4.85

4.85

Eighth, guarding the true Dharma: formerly one guarded views so that others could not shatter them, using skillful means to expound and propagate them; now one guards the various emptinesses of the three truths so that views cannot shatter them. If there is any stagnation, one skillfully expounds and disseminates them, sacrificing the body to preserve the Dharma, just as parents protect their child. This overturns and shatters the destruction of good deeds.
