首楞嚴義疏注經 7.81

7.81

散心持誦尚蒙擁護，況決定心求菩提者而不加護哉！既以菩薩精心冥熏神識，速得開發，自然記憶河沙劫事，無不了知。陰，冥也，又速召也。冥然感召，令開發也。

Even those who recite it with a scattered mind receive protection, so how could those seeking bodhi with a resolute mind not receive protection! Since the bodhisattvas' pure devotion secretly perfuses their spiritual consciousness, causing it to swiftly unfold, they naturally remember the events of aeons as numerous as the sands of the Ganges, comprehending all of them. *Yin* means secretly, and also means swiftly summoning. Secretly resonating and summoning, causing it to unfold.
