2.45

取非尼衣戒第四　一制意。有三種過。一者凡為下敬上仰奉情慇。所有財物思欲捨施。許無違從大僧非親多不籌量得便受之。令他財物竭盡。二有男女形別。理無脫三。涉財物既交思情。編親因事起染容壞梵行。臨危事撿可懼之甚。跡涉世譏致招誹謗。清白難分。莫能自拔以利諸過。是故聖制　二釋名可知　三別緣有五。一是比丘尼除下二眾。依祇下二眾衣不犯。多論下與尼同犯。二非親里除去親里不犯。三是應量是五衣。多論依者是應量衣吉。四虛心送與。謂乞得貿易不犯。五領受屬己即犯　四闕緣。比說。已下正明戒本。此戒因乞食比丘從蓮華尼受貴價僧伽梨衣。故佛便制戒。

The fourth precept: Taking a robe from an unrelated bhikṣuṇī. 1. Purpose of institution: There are three kinds of faults. First, generally speaking, an inferior respects a superior and looks up to them with deep devotion; whatever wealth and property they possess, they desire to give it away, yielding without defiance. When an ordained monk is unrelated, he often does not consider [their means] and accepts it as soon as he gets it, exhausting the other's property. Second, there is a bodily distinction between male and female, and in principle there is no escape [from suspicion]; when property is exchanged, thoughts and feelings arise, creating mutual intimacy; due to these matters defilement may arise, potentially destroying pure conduct. Being adjacent to perilous matters, one must be extremely cautious. Third, one's traces become involved in worldly criticism, attracting slander; purity and guilt become difficult to distinguish, and neither can extricate themselves, leading to various faults. For this reason, the Sage instituted the precept. 2. Explanation of the name: Can be known. 3. Specific conditions: There are five. First, she is a bhikṣuṇī, excluding the lower two assemblies; according to the Mahāsāṃghika Vinaya, robes from the lower two assemblies do not incur an offense, while the Sarvāstivāda-vinaya-vibhāṣā holds that the lower [assemblies] incur the same offense as with a bhikṣuṇī. Second, she is not a relative; excluding relatives, there is no offense. Third, it is of proper measure and is one of the five robes; according to the Sarvāstivāda-vinaya-vibhāṣā, if it is a robe of proper measure, it is a duṣkṛta. Fourth, given with empty mind (unreserved generosity); meaning if obtained by begging or through trade, there is no offense. Fifth, accepting it so that it belongs to oneself: immediately an offense is committed. 4. Incomplete conditions: Can be known by comparison. Below, the Prātimokṣa text is directly clarified. This precept arose because an alms-gathering bhikṣu accepted an expensive saṃghāṭī robe from the nun Utpalavarṇā; therefore the Buddha instituted the precept.
