成唯識論了義燈 7.264

7.264

答：隨前三果。准《瑜伽》說，必更修習諸善巧觀。隨所未斷，或復頓斷，如頓出離。或不出觀，次第漸斷，以更不取聲聞果故。若阿羅漢出無佛世，但修善巧斷餘習氣，練根成勝，無惑可斷。然《瑜伽》三十四云「又彼一切應知本來一向趣寂」者，據不逢佛一類者說，除麟角喻，餘若逢佛，成不定姓。

Answer: It corresponds to the previous three fruits. According to the Yogācārabhūmi, they must further cultivate the contemplations of skillfulness. Depending on what has not yet been severed, they may sever them suddenly, as in sudden departure; or, without emerging from contemplation, sever them sequentially and gradually, because they no longer take the śrāvaka fruit. If an arhat emerges in an era without a Buddha, they only cultivate skillfulness to sever the remaining residual impressions (vāsanā) and temper their faculties to become superior, there being no defilements to sever. However, when the thirty-fourth fascicle of the Yogācārabhūmi says, "Furthermore, all of them should be known as originally heading solely toward tranquility," it is spoken based on the class that does not encounter a Buddha; with the exception of the rhinoceros-horn-like ones, if the others encounter a Buddha, they become of indeterminate gotra.
