四分律行事鈔資持記 3.355

3.355

釋名中，初正釋。若下，反顯。準《業疏》中，具四義故，方名為淨。一增貪長慢，名污淨心；二外俗譏謗，名污淨信；三宿煮生罪，名污淨戒；四來受苦報，名污淨果。此下，遮濫。言從緣者，如上所釋，但取離過故；非對穢者，世愚多謂不結地穢故。

Under 'Explaining the Name,' first it explains directly. 'If...' below demonstrates by negation. Based on the Karma Commentary, because it possesses four meanings, it is only then called 'pure': first, increasing greed and fostering arrogance is called defiling the pure mind; second, worldly ridicule and slander from outside is called defiling pure faith; third, cooking overnight and generating offenses is called defiling pure precepts; fourth, receiving bitter retribution in the future is called defiling the pure fruit. 'This...' below prevents misinterpretation. The phrase 'in accordance with circumstances' is as explained above, merely taking the avoidance of faults as the standard; it is not in contrast to defilement, whereas the fools of the world mostly assume that it means the ground is defiled if not demarcated.
