2.845

釋第二中，上明開親。疏云以離損謗之緣故。義準四句，初二俱是親（不犯如上）；二二俱非親；三與線者親，織師非親（二句並墮）；四與線非親，織師是親（如下結吉）。與下，明輕犯。看織下，準律合有自織。繀，蘇內反，謂著絲於車也。

In explaining the second [condition], above it clarifies the exception for relatives. The commentary states that this is because it is free from the conditions of harm and slander. In meaning, it implies four propositions: first, both are relatives (no offense, as above); second, neither is a relative; third, the thread-giver is a relative, but the weaver is not a relative (both propositions incur a pāyattika); fourth, the thread-giver is not a relative, but the weaver is a relative (incurs a duṣkṛta, as below). From 'Giving...' onward, it clarifies minor offenses. From 'Watching the weaving...' onward: according to the Vinaya, it should include weaving oneself. *Suī*, fanqie of *su* and *nei*, means placing the silk onto the wheel.
