法苑珠林 41.13

41.13

若菩薩自手供養如來及支提不輕他人。不放逸。不懈怠。至心恭敬。不染污心。不於信心勝人所現諂曲求財。亦不以諸不淨物等供養。是名無染供養。

If a bodhisattva makes offerings to the Tathāgata and caityas with their own hands without looking down on others, without heedlessness or indolence, with utmost sincerity and respect, with an untainted mind, without feigning obsequiousness before superior persons of faith to seek wealth, and without making offerings of impure goods, this is termed an untainted offering.
