四分律行事鈔資持記 2.1210

2.1210

緣中。第二，《十誦》斷淫謂夫婦修梵行，受齊即八戒斷正淫故。三中，《五分》妨事者，令彼夫婦不得隨意故。《十誦》多人，即同第四人故。四中，三人外更有一人不犯，故云第四。《僧祇》簡非證人，彼律有比丘伴無犯，白衣雖多亦犯。《多論》二師父母尊人在座，不犯。《四分》開緣，並通道俗，不同《僧祇》。

Among the conditions: for the second, in the Daśādhyāya-vinaya "severing sexual activity" means the husband and wife cultivate celibacy, and receiving the upavāsa means severing proper sexual activity through the eight precepts. In the third, in the Mahīśāsaka-vinaya "obstructing business" means preventing that husband and wife from following their desires. In the Daśādhyāya-vinaya, "multiple persons" is identical to a fourth person. In the fourth, if there is another person besides the three persons, it is not an offense; hence it says "a fourth." The Mahāsāṃghika-vinaya excludes those who are not witnesses; in that vinaya, having a bhikṣu companion is no offense, but even if there are many white-clothed laypeople, it is still an offense. In the Sarvāstivāda Vinaya Vibhāṣā, if the two masters, parents, or venerated persons are seated, it is not an offense. The Dharmaguptaka's exceptions extend to both monastic and secular, unlike the Mahāsāṃghika-vinaya.
