大般涅槃經集解 65.18

65.18

案僧亮曰：身口意業皆是施體，有淨不淨，淨則福厚，不淨福薄。淨必由信，有心淨也。初三：一具二淨；餘二互有信心。雖有優劣，皆得稱淨。而或者聞說淨施由信，信是意業，便謂施具在意，故起諍也。

Sengliang states: Physical, verbal, and mental karmas are all the substance of giving. They are either pure or impure; if pure, the merit is abundant, and if impure, the merit is slight. Purity necessarily stems from faith, meaning there is mental purity. In the first three, one has both [faith and pure mind]; the remaining two have faith alternately. Although there are superiority and inferiority, all may be called pure. Yet deluded people, hearing it said that pure giving stems from faith and that faith is mental karma, thereupon claim that the requisites of giving reside only in the mind, thus giving rise to disputes.
