大方廣佛華嚴經隨疏演義鈔 62.58

62.58

疏「今初觀身」者，《瑜伽》明三各別有體，身是聚義，故外無情亦得名身。《智論》二意：前約三人修觀各別、後約一人修觀淺深。

Regarding the commentary's "Now first, contemplating the body": the Yogācārabhūmi explains that the three separately have their own essences; "body" has the meaning of an accumulation, so external insentient things may also be called "bodies." The Mahāprajñāpāramitā-upadeśa has two meanings: the former considers the cultivations of contemplation by three types of persons separately; the latter considers the shallowness and depth of contemplation cultivated by a single person.
