注大乘入楞伽經 4.12

4.12

意有三義，故取意為喻：一迅疾、二無礙、三遍到，以喻菩薩得如幻三昧，現形十方以化眾生，亦有此三義也。

Mind has three meanings, so the mind is taken as a metaphor: first, swiftness; second, unimpededness; third, universal reaching. This illustrates that when a bodhisattva attains the illusion-like samādhi and manifests forms in the ten directions to transform sentient beings, there are also these three meanings.
