四分律行事鈔資持記 2.18

2.18

本律三義。初斷頭者，即受法說相中，四喻之一；次云：如斷多羅樹心。三如針鼻缺，四如破石為二分；能喻雖四，同喻體壞；永障聖道，故云行法非用也。次無餘者，即遮法云：若遮無根無餘作等（殘為有餘，名亦出彼。）；行壞無功，不參眾務，故云絕分也。故下，引證。即律偈序，上卷已引。三不共住，名見戒本。問：與上無餘何異？答：上約己說，如彼死屍；下對僧論，如海飄出。對前祇律。初義頗同，此後二名，同彼第二。

The three meanings in our own Vinaya: First, "severed head" is one of the four similes given when explaining the marks during the reception of the Dharma. Next it says, "like severing the heart of a tāla tree"; third, "like a broken needle's eye"; fourth, "like splitting a stone in two." Although the illustrating similes are four, they equally illustrate the destruction of the entity; [the transgressor] is eternally hindered from the noble path, hence it says, "unfit for the practice of the Dharma." Next, "without remainder" refers to the exclusionary formula stating: "If one is excluded from performing acts with no basis and without remainder, etc." (The saṃghāvaśeṣa is "with remainder," which designation also derives from that.) One's practice being ruined, there is no merit, and one does not participate in the affairs of the saṃgha; hence it says, "cut off from any share." Therefore, below it cites proof—namely, the verse preface of the Vinaya, which was already cited in the upper fascicle. Third, "no longer dwelling together," which designation appears in the prātimokṣa. Question: How is this different from the above "without remainder"? Answer: The former is stated from the perspective of oneself, like a corpse; the latter is discussed with respect to the saṃgha, like being cast out by the ocean. In comparison with the previous Mahāsāṃghika-vinaya: the first meaning is quite similar; these latter two names correspond to its second meaning.
