thirteen major prohibitions ［十三僧残］ ( jūsan-sōzan): The second of the eight groups of precepts that constitute the two hundred and fifty precepts for fully ordained monks of the Hinayana teaching. This second group is called in Sanskrit samghāvashesha (temporary expulsion from the Buddhist Order). The first group consists of the four unpardonable offenses of killing, theft, having sexual relations, and lying, particularly claiming to have attained insight or understanding that one does not in fact possess. The thirteen major prohibitions are second to the first group in the gravity of the offenses they prohibit, and monks who violate one or another of these prohibitions are divested of membership in the Buddhist Order for a certain period. They are relieved from this punishment by repenting of their offense and confessing it before the other monks.
The thirteen major prohibitions are (1) ejaculating; (2) touching a woman’s body; (3) indecent talk with a woman; (4) pretending to be a monk of virtue in order to seduce a woman; (5) matchmaking or acting as an intermediary of adultery; (6) constructing a large dwelling without receiving approval from the Order concerning the size of the dwelling and the site of construction; (7) constructing a dwelling with funds donated by one’s patron without receiving approval from the Order concerning the site of construction; (8) groundlessly condemning another monk for having committed one of the four unpardonable offenses; (9) doing the same by skillful use of analogy; (10) attempting to cause disunity in the Order after being warned about it three times by other monks; (11) assisting a disrupter of the Order after being warned about it three times by other monks; (12) complaining about the Order and other monks when ordered by them to leave a particular region because of one’s evil deeds; and (13) rejecting other monks’ admonitions out of arrogance. The content of the thirteen major prohibitions differs according to the source.
