2.419

發行善根無有齊限。以諸淨國嚴飾之事成已佛土　增廣萬善嚴淨佛土依報行也　行無限施具足相好。除一切惡淨身口意　肇曰。行無限施者開四門施。求者所取無礙大施法也。又解。除垢惡以淨三業行大施。以嚴相好正報行也。

"To bring forth and practice roots of goodness without limits, and with the adornments of all pure lands to accomplish one's own Buddha-land"—this is the practice of circumstantial retribution, expanding the myriad good deeds to adorn and purify the Buddha-land. "To practice boundless giving, to be complete in the primary and secondary marks, and to remove all evils so as to purify body, speech, and mind." Zhao says: "Practicing boundless giving means opening the four gates to give; whatever seekers take is unhindered—this is the method of great giving. Another explanation: removing defilement and evil to purify the three karmas, and practicing great giving to adorn the primary and secondary marks—this is the practice of direct retribution."
