仁王護國般若經疏 3.19

3.19

From "sarvajña" onwards is the second, clarifying that the buddha fruit is empty. The text has three [parts]: now this is the first, clarifying that wisdom and severance are empty. "Sarvajña is also empty" is the emptiness of wisdom. "The emptiness of the fruit of extinction" is the emptiness of severance. "Or already empty before" is the emptiness of fundamental cause buddha-nature. Buddha-nature is fundamentally empty of itself, not made empty by deduction; hence it says "or already empty before". From "The Buddha attains the three unconditioned [dharmas]" onwards is the second, clarifying that the unconditioned is empty. "Extinction through deliberation" refers to the contemplation of mind; when the Buddha rightly contemplates the mind, extinguishing defilements, it is named extinction through deliberation. "Extinction not through deliberation" refers to the fundamental cause buddha-nature, whose nature is fundamentally pure of itself, without the defiling stains of afflictions, extinguishing delusions without toiling in contemplative practice. "Space" is that in which non-form appears. From "sarvajña" onwards is the third, concluding on the emptiness of the fruit, and so forth.
