大方廣佛華嚴經疏 28.39

28.39

三十二施手足二事合願，文但有三。初施行亦三：初標章引證。次「以信」下標因祈果。信為手因，果能雨寶；行為足因，果普遊步等。後「佛子」下淨心正施。於中初施手。「心願力」已下明施足心。如足住地能持身故，願住智地能成智身。離心垢故，能顯法身。法身湛然，故不可壞。智證永續，故無有斷。二「佛子」下明迴向行。文二：初廣辨一用，手能雨寶、足能遊剎。次「又令」下略舉諸手諸用。

Thirty-two: Giving the hands and feet combines the two matters into a single vow, and the text has only three parts. First, the practice of giving also has three parts: first, marking the section and citing precedents; next, from "With faith..." onward, marking the cause and praying for the fruit—faith is the cause for the hands, and its fruit is the ability to rain down treasures; action is the cause for the feet, and its fruit is universally striding about, and so forth; and finally, from "O sons of the Buddha..." onward, correctly giving with a pure mind. Within this, giving the hands comes first. From "the power of mental vows" onward, the mind of giving the feet is explained: just as feet resting on the earth can support the body, one vows to abide on the stage of wisdom and be able to accomplish the wisdom-body. Because it is free from the defilements of mind, it can manifest the dharmakāya. Because the dharmakāya is clear and serene, it cannot be destroyed. Because the realization of wisdom continues eternally, it is without interruption. Second, from "O sons of the Buddha..." onward, the practice of pariṇāmanā is explained. The text has two parts: first, it extensively explains a single function—the hands can rain down treasures, and the feet can travel through realms; next, from "further causing..." onward, it briefly adduces the multiple hands and multiple functions.
