大方廣佛華嚴經隨疏演義鈔 4.34

4.34

Regarding the commentary's statement, "Eighth, unimpededness between receptacle and resident": this was explained above within the causes. Moreover, it is because this body-cloud directly constitutes the entire physical world of receptacles. Therefore the sūtra states: "Or acting as sun and moon traveling through empty space, / or acting as rivers, pools, wells, and springs," and "Or sometimes acting as earth and water, / or again acting as wind and fire." The six propositions of mutual entering and mutual identity are all as explained before.
