四分律刪繁補闕行事鈔 2.203

2.203

獨與尼屏露坐戒二十六。四緣：一是比丘尼，二無第三人，三在屏露二處，四共坐便犯。《十誦》：屏處相去一丈墮，丈五吉羅；二丈若過不犯。《僧祇》：共一尼屏坐；或尼請一比丘食，一尼共比丘坐，一尼往來益食。益食去時，隨一一墮。比丘爾時應起，語言：「我欲起。」莫令彼疑作非法。若尼去者不犯。《多論》：比丘坐住屏覆處者，無慚愧處，可作淫處。律中見聞二屏，如二不定中說。若盲而不聾，聾而不盲，若立住，一切吉羅。不犯者：比丘有伴；若有知人，非盲聾；若行過倒地；若勢力持，命梵難者。

Precept twenty-six: sitting alone with a bhikṣuṇī in a screened or open place. There are four conditions: first, she is a bhikṣuṇī; second, there is no third person; third, in two types of places, screened or open; fourth, transgressing by sitting together. The Daśādhyāya-vinaya states: 'In a screened place, sitting one zhang apart is a pāyattika, one zhang five chi is a duṣkṛta; two zhang or more is no offense.' The Mahāsāṃghika-vinaya states: 'Sitting together with a single bhikṣuṇī in a screened place; or a bhikṣuṇī invites a bhikṣu for food, one bhikṣuṇī sits with the bhikṣu, and another bhikṣuṇī comes and goes serving additional food. When she who serves additional food leaves, each [departure] is a pāyattika. The bhikṣu at that time should stand up and say to her, "I wish to rise," so as not to cause the other to suspect an illicit act. If the bhikṣuṇī leaves, there is no offense.' The Sarvāstivāda-vinaya-vibhāṣā states: 'For a bhikṣu to sit or stay in a screened and covered place is a shameless place where sexual intercourse can be performed.' In the Vinaya, the two screened conditions of sight and hearing are as explained in the two aniyata offenses. If blind but not deaf, or deaf but not blind, or standing and staying, all are duṣkṛtas. As for non-offenses: the bhikṣu has a companion; there is a discerning person who is not blind or deaf; walking past and falling to the ground; or being constrained by force, or in cases of danger to life or brahmacarya.
