大方廣佛華嚴經疏 28.45

28.45

三十八施身皮。引例中，清淨藏菩薩未見同名。《智論》十六中如毒龍受一日戒，被剝五色皮，忍而施之云云。言金脇鹿王者，《智論》及《菩薩本緣集經》第四說。金脇鹿救於溺者，彼人背恩告王取鹿，大例名同而非施皮。願中云相好皮者，謂金色等。所為云淨佛剎者，皮為外相故。

Thirty-eight: Giving the skin of the body. Among the precedents cited, Bodhisattva Viśuddhagarbha has not been seen under the same name. In fascicle sixteen of the Dazhidulun, it is like the poisonous dragon that observed the one-day precepts: having its five-colored skin flayed, it patiently gave it away, and so on. The mention of the "king of deer with golden flanks" is as explained in the Dazhidulun and the Pusa benyuan ji jing, fascicle four. The deer with golden flanks rescued a drowning man; that man betrayed his kindness and informed the king to capture the deer; the broad precedent shares the same name, but was not the giving of skin. In the vow, "skin of marks and characteristics" refers to golden color and so forth. In the purpose, "purifying Buddha-fields" is because skin constitutes the external appearance.
