四分律行事鈔資持記 3.1072

3.1072

不犯中，初指本宗。律云：若有取與，及解救等觸，一切無欲心，不犯。次引他部。初是想差；若下，即急難。一切無著，顯上開意。非無吉者，制非儀故。

In [the section on] non-violation: first, pointing to our own school. The Vinaya states: if there is giving and taking, or contact while rescuing, etc., in all cases without lustful intent, there is no violation. Next, citing other schools: the first is an error in perception; from 'If...' onward refers to urgent distress. 'In all cases having no attachment' manifests the intention behind the above exceptions. That it is not without a duṣkṛta is because non-customary behavior is prohibited.
