首楞嚴義疏注經 8.113

8.113

方便空也，十心假也，一心中也。圓融妙慧名真方便，由此妙慧發前十信，以此十心本是一性所具功德。由妙慧發，令一一心皆具十心，十用無礙，一多相即，唯是一心。心即祕藏，今於此藏開發顯現，以不住法即住其中，名發心住。

Skillful means is emptiness, the ten minds are provisionality, and the one mind is the Middle. The completely interfused wondrous wisdom is called true skillful means. Due to this wondrous wisdom, the preceding ten faiths are aroused, because these ten minds are originally the virtues possessed by the one nature. Aroused by wondrous wisdom, each and every mind comes to possess all ten minds; the ten functions are unhindered, the one and the many are identical, and they are purely the one mind. The mind is itself the secret treasury; now opening and manifesting within this treasury, abiding within it by means of non-abiding dharmas, it is called the Abode of Arousing the Mind.
