法界圖記叢髓錄 1.69

1.69

又記云：七微者，窓遊塵、羊毛塵、兔毛塵、牛毛塵、金塵、水塵、極微塵也。解云：窓遊塵者，遊於窓隙日光也。羊毛塵者，析窓遊塵為七分故，唯止羊毛末也。兔毛塵者，析羊毛塵為七故，不止羊毛，唯止兔毛末也。牛毛塵者，析兔毛塵為七故，唯止牛腹下毛末也。析此為七者，透金而出，金不礙也。析此為七者，透過於水，水不能潤也。析此為七者，是極微也。此一一塵皆生子故，名七母塵也。此極微塵，於初教中三無數劫分而析之。約此初教之塵，於終教中不可計劫分而析之。至一乘中二佛世界塵數劫中分而析之，至最細際方為一乘極微塵也。

Another record says: The seven subtle [dusts] are window-wandering dust, sheep-hair dust, hare-hair dust, ox-hair dust, gold dust, water dust, and ultimate atom. Explanation: 'Window-wandering dust' wanders in the sunlight through a window aperture. 'Sheep-hair dust': because window-wandering dust is divided into seven parts, it rests only on the tip of a sheep's hair. 'Hare-hair dust': because sheep-hair dust is divided into seven, it does not rest on a sheep's hair, but rests only on the tip of a hare's hair. 'Ox-hair dust': because hare-hair dust is divided into seven, it rests only on the tip of a hair under an ox's belly. Dividing this into seven penetrates through gold and emerges, unimpeded by gold. Dividing this into seven penetrates through water, unable to be moistened by water. Dividing this into seven is the ultimate atom. Because each of these dusts generates offspring, they are called the seven mother dusts. In the initial teaching, this ultimate atom is divided and analyzed over three incalculable eons. In terms of this dust of the initial teaching, it is divided and analyzed over incalculable eons in the final teaching. When reaching the One Vehicle, it is divided and analyzed over eons as numerous as the dust motes of two Buddha-worlds, and only when reaching the most subtle limit does it become the ultimate atom of the One Vehicle.
