首楞嚴義疏注經 3.447

3.447

「汝全不知，如來藏中，性覺真空、性空真覺，清淨本然，周遍法界，隨眾生心、應所知量。阿難！如一井空，空生一井，十方虛空亦復如是，圓滿十方，寧有方所？循業發現。」

"You do not know at all that within the tathāgatagarbha, the nature of awareness is true emptiness, and the nature of emptiness is true awareness. Pure and fundamental, it pervades the dharmadhātu, responding according to the capacity of sentient beings' minds and corresponding to what they know. Ānanda! Just as the space of one well produces the space for one well, the space in the ten directions is also like this: filling the ten directions completely, how could it have a fixed location? It is discovered according to karma."
