維摩經略疏 1.68

1.68

三、觀心明者，即是三觀明四如是。《華嚴》云「欲知如來心，但觀眾生心。若見如來心，即見眾生心。」如破一微塵出大千經卷，眾生一念無明因緣所生之心即具四理。若觀心因緣生滅入空，即生滅如是即空。即假即中，例說可知。

Third, the explanation by contemplation of mind: this is elucidating the four "Thus" by means of the threefold contemplation. The Avataṃsaka says: "If you wish to know the Tathāgata's mind, just contemplate the mind of sentient beings. If you see the Tathāgata's mind, you see the mind of sentient beings." Just as crushing a single atom releases sūtra scrolls of a trichiliocosm, a single thought of sentient beings born from the conditions of ignorance inherently possesses the four principles. If one contemplates that the mind's conditioned arising and perishing enters emptiness, then arising-and-perishing "Thus" is identity with emptiness. Its identity with the provisional and identity with the middle may be known by analogy.
