維摩經略疏 1.84

1.84

次、用四教明住義者，隨教所辨法門不同，佛於中住憐愍眾生，故示住毘耶。三、約觀心者，《華嚴》云「欲見如來心，但觀眾生心。」何者？一心三觀圓觀三諦開佛知見，雖有肉眼名為佛眼亦名種智。若用三智，以不住法住三諦三昧，亦是佛所得法。佛於中住，憐愍眾生，不捨道法現凡夫事，住世間法也。此須善用六即分別，入大乘之要門也。

Next, using the four teachings to explain the meaning of "abiding": according to the different Dharma-gates distinguished by each teaching, the Buddha abides within them; out of pity for sentient beings, he therefore manifests abiding in Vaiśālī. Third, in terms of the contemplation of mind: the Avataṃsaka Sūtra states, "If you wish to see the Tathāgata's mind, merely contemplate the mind of sentient beings." Why? The threefold contemplation in a single mind comprehensively contemplates the three truths to open the Buddha's knowledge and vision; although one possesses physical eyes, they are named the Buddha eye and also named the wisdom of all species. If one uses the three wisdoms to abide in the samādhi of the three truths through the dharma of non-abiding, this is also the dharma attained by the Buddha. The Buddha abides within it; out of pity for sentient beings, without abandoning the Dharma of the Way, he manifests the affairs of ordinary beings and abides in worldly dharmas. In this, one must skillfully use the distinction of the six identities, which is the essential gate for entering the Mahāyāna.
