四分律刪繁補闕行事鈔 2.11

2.11

初言波羅夷者。《僧祇》義當極惡。三意釋之：一者退沒，由犯此戒，道果無分故。二者不共住，非失道而已，更不入二種僧數。三者墮落，捨此身已，墮在阿鼻地獄故。《十誦》云：墮不如意處。《薩婆多》解云：由與魔鬪，以犯此戒，便墮負處。《四分》云：波羅夷者，譬如斷人頭，不可復起；若犯此法，不復成比丘故；此從行法非用為名。又云：波羅夷者，無餘也；此從眾法絕分為名；故偈云：「諸作惡行者，猶如彼死尸，眾所不容受，以此當持戒。」又名不共住者，不得於說戒、羯磨二種僧中共住故。

First, pārājika: the Mahāsāṃghika-vinaya takes its meaning to be extreme evil. It is explained with three meanings: First, falling back and submerging, because by committing this offense one has no share in the fruits of the Path. Second, non-cohabitation, because not only does one lose the Path, but one no longer enters into the count of either of the two kinds of saṃgha. Third, falling down, because after relinquishing this body, one falls into the Avīci hell. The Daśādhyāya-vinaya says: falling into an undesirable place. The Sarvāstivāda explains: from fighting with Māra, by committing this offense, one immediately falls into defeat. The Dharmaguptaka Vinaya says: pārājika is like severing a person's head, which cannot be restored; if one commits this offense, one is no longer a bhikṣu; this is named after the practice being rendered unusable. It also says: pārājika means without remainder; this is named after having one's share cut off from communal acts; hence the verse says: 'Those who commit evil deeds / Are just like a corpse, / Not tolerated by the community; / Therefore one must maintain the precepts.' It is also called non-cohabitation because one may not cohabit within the two kinds of saṃgha of upoṣadha recitation and karman.
