大乘入道次第 1.52

問：此加行位能觀遍計心境皆空，何不此時即證真如？答：此位雖觀遍計心境，而猶未能除空有相。由有此相，不能證理。要二相亡，方達真理。故《唯識》云：「以彼空有二相未除，帶相觀心有所得故，非實安住真唯識理。彼相滅已，方實安住。」

Question: In this stage of preparatory application, one can contemplate that both the imagined mind and objects are empty; why does one not realize tathatā at this very time? The answer: Although in this stage one contemplates the imagined mind and objects, one is still unable to eliminate the signs of emptiness and existence. Due to the presence of these signs, one cannot realize the principle. Only when both signs are eliminated can one penetrate the true principle. Thus the Cheng weishi lun says: "Because those two signs of emptiness and existence have not yet been eliminated, and because contemplating the mind accompanied by signs involves apprehension (upalambha), one does not truly abide in the principle of true representation-only. Only when those signs have been extinguished does one truly abide."
