四分律比丘含注戒本 1.67

1.67

佛言：「譬如斷人頭，不可復起，比丘亦如是，犯此法者不復成比丘，故名也。若方便欲行不淨，成者波羅夷，不成者偷蘭遮。若教比丘行，若作，教者偷蘭遮；不作，突吉羅。除比丘、比丘尼，餘眾相教，作、不作盡突吉羅。若屍半壞，若一切壞，若骨間，若地孔、泥孔，行不淨者，並偷蘭。若道，作道想，若疑，若非道想，並波羅夷。若非道，道想，道疑，並偷蘭遮。比丘尼波羅夷。式叉摩那、沙彌、沙彌尼，突吉羅，滅擯。是謂為犯。不犯者，若睡眠無所覺知，不受樂，一切無有婬意。不犯者，最初未制戒，癡狂、心亂、痛惱所纏。」

The Buddha said: "Just as a person whose head is cut off cannot rise again, so too is the bhikṣu: one who violates this dharma no longer remains a bhikṣu; hence it is so named. If with an expedient means he wishes to perform an act of impurity: if completed, it is a pārājika; if not completed, it is a sthūlātyaya. If he instructs another bhikṣu to perform it: if the latter does so, the instructor commits a sthūlātyaya; if he does not do so, a duṣkṛta. Except for bhikṣus and bhikṣuṇīs, when the remaining assemblies instruct one another, whether performed or not, all commit a duṣkṛta. If one performs an act of impurity upon a half-decayed corpse, a wholly decayed corpse, between bones, in a hole in the ground, or in a hole in the mud, all are sthūlātyaya. If it is a tract and he perceives it as a tract, or has doubt, or perceives it as a non-tract, all are pārājika. If it is a non-tract, and he perceives it as a tract or has doubt of its being a tract, all are sthūlātyaya. For a bhikṣuṇī, it is a pārājika. For a śikṣamāṇā, a śrāmaṇera, or a śrāmaṇerī, it is a duṣkṛta and expulsion. These are what constitute offenses. As for non-offenses: if during sleep one is without awareness, receives no pleasure, and is entirely free of lustful intent. Furthermore, non-offenders are: the first perpetrator before the precept was instituted, or one who is mad, mentally disordered, or tormented by severe pain."
