大方廣佛華嚴經疏 49.46

49.46

第二喻中二：先明大經潛塵，以喻上文妄纏佛智。大經卷者，佛智無涯，性德圓滿也。書各稱境者，智如理故。潛一塵者，略有三義：一妄覆真故、二小含大故、三一具多故。一切塵者，無一眾生不具佛智故。後「時有一人」下出經益物，喻上離妄現前。

The second part, the metaphor, has two sections: first, it explains that the great sūtra is hidden within an atom to illustrate what was said above about Buddha-wisdom being entangled by delusion. As for 'a scroll of a great sūtra', Buddha-wisdom is boundless, and the virtues of its nature are consummately complete. 'Each written according with its object' is because wisdom corresponds to noumenon. Being hidden within a single atom has, in brief, three senses: first, because the deluded veils the true; second, because the small contains the great; and third, because the one possesses the many. As for 'all atoms', it is because there is not a single sentient being who does not possess Buddha-wisdom. Later, from 'At that time, there was a person' onward, it brings forth the sūtra to benefit beings, illustrating what was said above about leaving behind delusion so that it manifests before them.
