華嚴經旨歸 1.93

1.93

六、深定力故者，謂彼自在三昧力故，令於小處而現大法，無所障礙。下文云「入微塵數諸三昧，一一三昧生塵等定，一塵中現無量剎，而彼微塵亦不增。」乃至云「是名大仙三昧力」。

Sixth, "because of the power of deep samādhi" means that through the power of that sovereign samādhi, great phenomena are made to appear in a small place without any obstruction. Later in the text it says: "Entering samādhis as numerous as fine dust motes, / Each samādhi produces absorptions equal to dust motes; / In a single dust mote, immeasurable lands appear, / Yet that fine dust mote does not increase." Up to: "This is called the samādhi power of the Great Sage."
