首楞嚴義疏注經 4.190

4.190

真妙覺明，合虛空無相也。汝以下合諸相發揮。汝心分別有空發明，妙覺明心隨現空相；地水火風於汝心中各各互發，隨心各現；心中俱發，七大俱現。又隨人各發，人各見別；多人俱發，俱現一相。此即真如不守自性，隨緣所現有種種相。上文云「隨眾生心，應所知量，循業發現。」《起信論》中「因熏習鏡現諸境界」，亦此意也。

'True wonderful enlightenment and clarity' corresponds to empty space having no characteristics. From 'if you' downwards corresponds to the display of the various characteristics. When your mind discriminates and brings forth emptiness, the mind of wonderful enlightenment and clarity manifests the characteristic of emptiness accordingly. When earth, water, fire, and wind are each brought forth in your mind, they each manifest according to the mind; when brought forth together in the mind, the seven great elements appear together. Furthermore, as different people bring them forth, each person sees differently; when many people bring them forth together, they all manifest a single characteristic. This is precisely tathatā not holding to its own nature, manifesting diverse characteristics according to conditions. The preceding text says: 'According to the minds of sentient beings, responding to their capacity of knowledge, manifesting in accordance with their karma.' The Awakening of Faith's statement that 'because of the perfuming mirror, various realms appear' also has this meaning.
