楞伽阿跋多羅寶經註解 1.528

1.528

如來之意正欲說實，而未說者，機未熟耳，故云「彼心無真實」。由無真實故，如來說藏識轉生諸識，如海起浪，及鏡中之像、夢中之事雖一時俱現，皆非真實，故曰「心境界亦然」也。

The Tathāgata's intention was precisely to speak of reality, yet that he did not speak of it was simply because their capacities were not yet ripe; hence he said: "Their minds have no reality." Because there is no reality, the Tathāgata explained that the storehouse consciousness evolves to produce the various consciousnesses, just as the ocean produces waves, and that although images in a mirror and events in a dream all appear at the same time, none are real; hence he stated: "The realms of mind are also like this."
