問：既言真如舉體作一微塵，則隨拈一一微塵，亦各具此四種大義否？答：具。以微塵相若無方分則非微塵，以無形故。若有方分，則可分析，定非實有。推此微塵，既無相故，則一切法亦皆無相，即真實空大義。微塵之相既不可得，即一切法圓滿成就無能壞性，一切世間境界之相皆於微塵中現，不出不入、不滅不壞，乃至微塵具足無邊無漏功德，為因熏習一切眾生心故，即真實不空大義。以達此一微塵性，即是真實不空體故，二障永斷，本性常住，即是離障大義。以此一微塵性離二障故，隨所應化，現身說法，令修善根，所謂於一毛端現寶王剎，坐微塵裡轉大法輪，即示現大義也。《華嚴經》云「一微塵中具足大千經卷。如一微塵，一切微塵亦復如是。」此之謂也。思之！初釋覺義竟。

Question: Since it is said that the entire essence of tathatā constitutes a single speck of dust, then wherever one picks up any single speck of dust, does it also each possess these four kinds of great meaning? Answer: It possesses them. Because if a speck of dust has no spatial divisions, it is not a speck of dust, since it would lack form. If it has spatial divisions, it can be analyzed and is definitely not truly existent. When investigating this speck of dust, since it has no marks, all phenomena are likewise without marks, which is the great meaning of the genuinely empty. Since the marks of a speck of dust cannot be apprehended, it is the indestructible nature that fully accomplishes all phenomena; the marks of all worldly realms are manifested within a speck of dust, neither going out nor coming in, neither perishing nor being destroyed, and even a speck of dust is fully endowed with boundless, untainted merits, which serve as the cause to perfume the minds of all sentient beings—this is the great meaning of the genuinely non-empty. Because realizing the nature of this single speck of dust is itself the genuinely non-empty essence, the two hindrances are forever cut off and the fundamental nature is eternally abiding, which is the great meaning of separation from hindrances. Because this nature of a single speck of dust is separated from the two hindrances, it manifests bodies and expounds the Dharma in response to those to be transformed, causing them to cultivate good roots—the so-called manifesting the jeweled king's realm on the tip of a single hair, and turning the great Dharma wheel while sitting inside a speck of dust—this is the great meaning of manifestation. The Avataṃsaka Sūtra says: 'A single speck of dust fully contains a scripture of the great chiliocosm; as with a single speck of dust, so it is with all specks of dust.' This is what it refers to. Reflect upon this! The first section, explaining the meaning of enlightenment, is concluded.
