大方廣佛華嚴經隨疏演義鈔 50.2

50.2

疏「如不思議品十種勇健法中第一法說」者，經云「謂一切諸佛身不可壞、命不可斷，乃至云八部天龍盡其勢力雨大金剛山，如須彌山及鐵圍山，遍於三千大千世界一時俱下，不能令佛心有驚怖，乃至一毛亦不搖動。」

Regarding the commentary's phrase "as explained in the first dharma among the ten kinds of courageous and powerful dharmas in the chapter on the Inconceivable": the sūtra states, "Namely, the bodies of all buddhas cannot be destroyed, their lifespans cannot be severed, up to: even if the eight classes of gods and dragons exhaust their power to rain down great vajra mountains like Mount Sumeru and the Cakravāḍa iron mountains all at once everywhere throughout the trichiliocosm, they cannot cause fear in the Buddha's mind, nor can they shake even a single hair."
