大方廣佛華嚴經隨疏演義鈔 33.16

33.16

疏「內身揀於外器及他身」者，釋初偈內身二字以念處。然四地中有於三身，然《智論》、《瑜伽》各有解釋，今即《瑜伽》意：一以自身為內身、二以器物缾衣車乘等為外身、三以外有情妻子男女等為內外身，故今揀於後二。

Regarding the commentary's "the internal body is distinguished from the external vessel and the bodies of others": this explains the two words 'internal body' in the first verse by means of the applications of mindfulness. Now, in the fourth bhūmi there are three bodies, and the *Mahāprajñāpāramitopadeśa* and the *Yogācārabhūmi* each have explanations. Here it follows the intent of the *Yogācārabhūmi*: 1. taking one's own body as the internal body; 2. taking external implements such as vases, clothes, and vehicles as the external body; 3. taking external sentient beings such as wives, children, boys, and girls as the internal-external body. Therefore, it now sets apart the latter two.
