首楞嚴義疏注經 6.137

6.137

標也。妙容多現，不可以形量拘。祕呪無邊，不可以言說取。此則由三昧力熏本慈無量心，現種種形、說種種呪，令諸見聞獲其妙樂。

Raising the point. Wondrous forms manifest in great numbers, unconstrained by physical limits. Secret dhāraṇīs are boundless, not graspable by speech. This is due to the power of samādhi perfuming the original immeasurable loving-kindness, manifesting various forms and uttering various dhāraṇīs to cause all who see and hear to obtain wondrous joy.
