6.81

There are three antidotes: two are expedients, and one is the primary cultivation. As for the two expedients: the first is carefully examining and observing, awakening to the fact that all are demonic events, so that not a single thought of confusion arises; the second is personally reflecting that one's roots of goodness are slight and thin and karmic obstacles are deep and heavy, turning back to reprove oneself, repenting errors and turning toward goodness. The one primary cultivation is contemplating that all of them are mind-only, that there are no phenomena outside the mind, not departing from the samādhi of one mark.
