大乘起信論裂網疏 5.12

5.12

一切境相唯是妄心之所分別；若離妄心，即境界相滅。唯真如心無所不遍，此是如來自性如虛空義，非謂如空是常是有。

All object-aspects are merely discriminated by the deluded mind; if one is free from the deluded mind, then the characteristics of objective realms cease. Only the mind of tathatā is all-pervading; this is the meaning of the Tathāgata's self-nature being like empty space, not that it is eternal and existent like empty space.
