妙法蓮華經玄義 2.7

2.7

心法妙者，如〈安樂行〉中，修攝其心，觀一切法，不動不退。又一念隨喜等。《普賢觀》云：「我心自空，罪福無主」「觀心無心，法不住法。」又「心純是法」。《淨名》云：「觀身實相，觀佛亦然。諸佛解脫當於眾生心行中求。」《華嚴》云：「心、佛及眾生，是三無差別」「破心微塵，出大千經卷」，是名心法妙也。

Regarding the profundity of the dharmas of mind: as in the chapter 'Comfortable Conduct', cultivating and gathering one's mind, one contemplates all dharmas as unmoving and non-regressing. There is also the single moment of rejoicing, and so forth. The Samantabhadra-dhyāna-sūtra says: 'My mind is inherently empty; sin and merit have no master,' and 'Contemplating the mind, there is no mind; dharmas do not abide in dharmas.' It also says: 'Mind is purely Dharma.' The Vimalakīrtinirdeśa says: 'Contemplating the real mark of the body, one contemplates the Buddha likewise. The liberation of all buddhas should be sought within the mental conduct of sentient beings.' The Avataṃsaka-sūtra says: 'Mind, buddha, and sentient beings—these three are without distinction,' and 'Breaking open a fine atom of the mind brings forth scrolls of sūtras of a trichiliocosm.' This is called the profundity of the dharmas of mind.
