3.31

損益門有八者，初七則是身三語四，如次配之，八合是意三業道，亦可前亦則前六種，第七、第八諸業共引。

Regarding the ‘eight doors of harm and benefit’: the first seven are the three of body and four of speech, paired respectively; the eighth combined comprises the three paths of mental karma. Alternatively, the previous ones are the first six kinds, and the seventh and eighth are commonly induced by all karmas.
