684.6

佛告比丘：「諦聽，善思，當為汝說。如來、應、等正覺者，先未聞法，能自覺知，現法自知，得三菩提，於未來世能說正法，覺諸聲聞，所謂四念處、四正斷、四如意足、五根、五力、七覺分、八聖道分，是名如來、應、等正覺。所未得法能得，未制梵行能制，能善知道、善說道，為眾將導，然後聲聞成就隨法隨道，樂奉大師教誡、教授，善於正法，是名如來應等正覺、阿羅漢慧解脫種種別異。

The Buddha told the monks, “Listen closely, and consider it well. I’ll explain this for you. Before the teaching had yet to be heard, the Tathāgata, Arhat, and Completely Awakened One realized and knew it himself. Knowing it himself in the present life, he attained complete awakening. He was able at a future time to explain the correct teaching that awakened his disciples, namely the four abodes of mindfulness, four right efforts, four mental abilities, five faculties, five powers, seven factors of awakening, and the eightfold path. This is called the Tathāgata, Arhat, and Completely Awakened One.

“He attained the teaching that had yet to be attained, managed the religious practice that had yet to be managed, and well knew the path that he knows well as the leader of this assembly. Afterward, his disciples succeeded in following the teaching and the path. They are delighted and appreciate the great teacher’s instruction, teaching, and skill in the correct Dharma. These are called the various differences between the Tathāgata, Arhat, and Completely Awakened One and the arhat who’s liberated by wisdom.
