4.333

見修等者，謂上二界各有三種修惑，謂貪、癡、慢。此惑微細難除，故約八地分之。每地分成九品，都合七十二品。每品各有一無間、一解脫，斷至七十一品名阿羅漢向，斷七十二品惑盡成阿羅漢。此果斷惑如登樓臺漸陟漸高。見修合論，兼欲界一地，總以八十九品無為，為此果體。

"Seeing and cultivating, etc." means that the upper two realms each have three kinds of afflictions of cultivation, namely greed, ignorance, and arrogance. These afflictions are subtle and hard to eliminate, so they are divided across the eight grounds. Each ground is divided into nine grades, making seventy-two grades in all. Each grade has one uninterrupted path and one liberation path; severing up to seventy-one grades is called approaching an arhat, and severing all seventy-two grades of afflictions is becoming an arhat. Severing afflictions for this fruit is like climbing a storied pavilion, stepping gradually higher. Considering seeing and cultivating together, combining the one ground of the desire realm, eighty-nine grades of asaṃskṛta in total serve as the essence of this fruit.
