大方廣佛華嚴經疏 50.29

50.29

第七「復次佛子譬如幻師」下存亡亙現。由順機故，此滅彼存，非如來身不能長久。前喻約見滅見成，此喻約常見不見。

Seventh, from "Furthermore, bodhisattvas, like a magician..." onward, presence and absence mutually appearing. Due to complying with capacities, here it ceases and there it remains, not that the Tathāgata's body cannot endure long. The previous simile was in terms of seeing cessation and seeing attainment; this simile is in terms of constantly seeing and not seeing.
