大方廣佛華嚴經隨疏演義鈔 29.39

29.39

第五釋文。疏「智論云：足下放」者，身得住處，故云於足。即第九論，釋經從足下千輻輪相中放六百萬億光明，表說六度故。義有兩意，此是初意。第二意云：復次一身中，雖頭貴而足賤，佛不自貴光、不為利養，是故於賤處放光。彼約教相，故作是釋；今文約表，故不正用，即是第二最卑微故攝之。

Fifth, explaining the text. Regarding the commentary's "The Treatise [on the Great Perfection of Wisdom] says: emitted from beneath the feet": the body finds a place to stand, hence it is said to be from the feet. This is in the ninth fascicle of the treatise, explaining the sūtra's emitting six hundred trillion rays of light from the thousand-spoked wheel marks beneath the feet, signifying the preaching of the six pāramitās. There are two meanings: this is the first meaning. The second meaning says: furthermore, within a single body, although the head is noble and the feet are lowly, the Buddha does not hold light as noble for himself nor does he do it for gain and offerings; therefore he emits light from a lowly place. That text was in terms of doctrinal characteristics, hence making this explanation; the present text is in terms of symbolism, so it does not directly employ that, which is subsumed under the second [point] of being the most humble.
