仁王般若經疏 3.122

3.122

譬如下，譬說。云譬如有人登大高臺者，即如來地。三藏師云：譬有五。一最高，一切頂故。二真實不壞，如佛果常住難登。三還源，越凡聖故。四自性寂靜，如佛無生滅故。五安樂依處，如寂觀照無不了故。言住理盡三昧亦復如是者，合譬也。常修一切行下，第三結勸位。入婆伽度位者，此云施德地，以能雲雨說法，故亦名破度地。定慧具足，故云佛慧三昧也。

From "For example" onward is the exposition by analogy. Where it says "for example, just as when someone ascends a grand, high tower," this is the Tathāgata ground. The Tripiṭaka Master says: There are five [aspects to the] analogy: 1. the highest, because it is the summit of all; 2. real and indestructible, like the Buddha fruit which is eternally abiding and difficult to scale; 3. returning to the source, transcending both ordinary beings and nobles; 4. intrinsically tranquil, like the Buddha being free from arising and ceasing; 5. a resting place of peace and bliss, just as in tranquil contemplation and illumination nothing is not seen clearly. Where it says "abiding in the samādhi of exhausting principle is also like this," this is the application of the analogy. From "Constantly cultivating all practices" onward is the third [part], concluding and encouraging [entry into] the stage. "Entering the bhagavat stage" is translated here as "the stage of bestowing virtue"; because one can shower the Dharma like clouds and rain, it is also called "the stage of delivering through destruction." Meditation and wisdom being complete, it is therefore called "the Buddha-wisdom samādhi."
