四分律行事鈔資持記 2.473

2.473

次科為二，先引論三義。初即通意，通一切故。二止謗者，論釋云：世人外道，當言沙門釋子作不淨行，與俗無異。三生信者，論云：雖復屏處，諸天善神一切見之。四下，次引律訶詞，翻顯制意。為令行淨，堪受施故。四部文同，彰其意切。縱不為失，以手捫陰，極為鄙賤。世多有之。請以斯語反自剋責，寧無愧乎！

The next subsection has two parts: first, it cites three meanings from the treatise. The first is the general meaning, because it applies generally to all [precepts]. The second, to stop slander, is explained in the treatise: 'Worldly people and non-Buddhists would say that the renunciant sons of the Śākya practice impure deeds, no different from laypeople.' The third, to produce faith, is stated in the treatise: 'Although it be in a secluded place, all the heavenly beings and good spirits see it.' From 'fourth' downward, it next cites the words of rebuke from the Vinaya to reveal conversely the intention behind the prohibition: to make practice pure so that one is worthy of receiving donations. The texts of the four Vinayas are identical, manifesting how pressing their intention is. Even if not for the purpose of emission, touching the genitals with the hand is exceedingly base and vile. It often occurs in the world. Please use these words to reprove yourself; could you be without shame?
