瑜伽論記 3.15

3.15

無間業同分者，謂無間業同類之罪，基云：污阿羅漢尼及母，是害母類，打最後有菩薩，是殺父類；或於天廟等行殺；或於委重所損害；或於貧苦田施無畏已返逼惱，是殺阿羅漢類。

Those of the same class as inexpiable karmas refers to offenses of the same category as inexpiable karmas. Ji states: defiling an arhat nun or one's mother belongs to the category of matricide; striking a bodhisattva in his final existence belongs to the category of patricide; or committing murder in a divine shrine and the like, or causing injury to one who has been entrusted, or first granting fearlessness to a field of poverty and affliction and then turning to torment them, belongs to the category of killing an arhat.
