四分戒本疏卷第一．第二．第三 2.35

2.35

若比丘共女人在露現處不可作婬坐作麁惡語有住信優婆種於二法中以一一法說若僧伽婆尸沙若波逸提是坐比丘自言我犯是事於二法中應一一治若僧伽婆尸沙若波逸提如住信優婆種所說應如法治是比丘是名不定法　此戒句同前亦四。一至麁語犯不定。二有住信下舉不定。二是比丘下自言不定。四如住信下治罪不定。但罪二三不同。餘義皆等前戒。故不重釋。已下廣辯文句。初文亦六。一一牒釋。若比丘者同前。女人者亦爾。露現處者。謂無牆壁障也。不可作婬處者。不容行婬處也。作麁惡語者。說婬欲不淨行。讚嘆二道好惡。此上六句此是犯不定。已下諸句文義同上。

"If a bhikṣu sits with a woman in an open, visible place unsuitable for engaging in sexual intercourse, and utters coarse and wicked words, and a trustworthy upāsikā charges [him] according to one of the two rules—either a saṃghāvaśeṣa or a prāyaścittika—and the sitting bhikṣu confesses, 'I committed this matter,' he should be dealt with according to whichever of the two rules [he confessed to]—either a saṃghāvaśeṣa or a prāyaścittika; as stated by the trustworthy upāsikā, he should be dealt with in accordance with the Dharma: this bhikṣu [is subject to what] is called an indeterminate rule."
The clauses of this precept are the same as before, also being four: First, up to "coarse words" is the indeterminacy of the offense. Second, from "and a trustworthy" onward is the indeterminacy of the charge. Third, from "and the sitting bhikṣu" onward is the indeterminacy of the confession. Fourth, from "as stated by the trustworthy" onward is the indeterminacy of dealing with the offense. It is only that the offenses differ between two and three; the remaining meanings are all equal to the previous precept, and therefore are not explained again.
Below, the clauses of the text are distinguished in detail. The first section also has six; they are cited and explained one by one:
"If a bhikṣu": the same as before.
"A woman": likewise.
"An open, visible place": meaning without the obstruction of walls.
"A place unsuitable for engaging in sexual intercourse": a place incapable of accommodating the act of sexual intercourse.
"Utters coarse and wicked words": speaking of sexual desire and impure conduct, praising or disparaging the two tracts.
The above six clauses constitute the indeterminacy of the offense. The subsequent clauses are identical in text and meaning to the above.
