7.364

釋曰：類智有二：一、真；二、俗。今此所明約俗類說。若真類智，必緣於上，如上下諦八類智也。既善習者能了於上，明善自在亦能修上，俱曾得故。

Explanation: Subsequent wisdom is of two kinds: first, genuine; second, conventional. What is clarified here is stated with respect to conventional subsequent wisdom. If it is genuine subsequent wisdom, it must take the higher realms as object, just as the eight subsequent wisdoms take the higher and lower truths as objects. Since one who has practiced well can discern the higher realms, it is clear that one with wholesome mastery can also cultivate the higher realms, because both have been previously attained.
