12.84

The sūtra says: fifth, "the equality of tranquility". The meaning here is that defilement is fundamentally tranquil. If relying on Ji's explanation, the sixth is the illuminating wisdom; therefore the fifth and sixth are both discussed with respect to tathatā. The Tripiṭaka Master divides this single clause, "because of the equality of being ultimately and fundamentally quiescent", into two, forming the fifth and sixth: the equality of tranquility and the equality of fundamental purity; and the next clause below is separately the seventh equality.
