摩訶止觀 3.180

云何出世名教皆從心起？堅意《寶性論》云：「有一大經卷，如三千大千世界大，記大千世界事。如中、如小，四天下、三界等大者，皆記其事在一微塵中。一塵既然，一切塵亦爾。一人出世，以淨天眼見此大經卷，而作是念：『云何大經在微塵內，而不饒益一切眾生？』即以方便，破出此經，以益於他。」如來無礙智慧經卷，具在眾生身中；顛倒覆之，不信、不見。佛教眾生修八聖道，破一切虛妄，見己智慧與如來等。此約微塵，附有為喻。

How do supramundane designations and teachings all arise from the mind? Sthiramati's *Ratnagotravibhāga* states: 'There is a great sūtra scroll as vast as the trichiliocosm, recording the affairs of the trichiliocosm. Things as vast as medium, small, the four continents, or the three realms have their affairs recorded within a single dust mote. As it is with one dust mote, so it is with all dust motes. A person appears in the world and, with the pure divine eye, sees this great sūtra scroll and thinks: "Why is this great sūtra inside a dust mote without benefiting all sentient beings?" He then uses expedients to break it open and bring forth this sūtra to benefit others.' The Tathāgata's unhindered wisdom sūtra scroll is fully present within the bodies of sentient beings; inversions conceal it, so they neither believe nor see it. The Buddha teaches sentient beings to cultivate the eightfold noble path, shatter all falsehood, and see that their own wisdom is equal to that of the Tathāgata. This draws upon a dust mote to provide a simile based on existence.
