妙法蓮華經文句 2.176

2.176

觀行者，動六根也，地相堅固如六根水執，未曾入大乘之道，動難動之地，表淨未淨之根。東涌西沒者，東方青主肝，肝主眼；西方白主肺，肺主鼻，此表眼根功德生、鼻根煩惱互滅，鼻根功德生、眼中煩惱互滅，餘方涌沒表餘根生滅亦復如是。六動者，動、起、涌、震、吼、覺，一一中又有三：謂動、遍動、等遍動。直動為動，四天下動為遍動，大千動為等遍動。餘五亦如是，合十八種動，此即表淨十八界也（云云）。

In terms of the contemplation of practice: it moves the six sense faculties. The mark of the earth is solid, like the rigid attachments of the six sense faculties, which had never entered the path of the Mahāyāna; moving the earth that is hard to move represents purifying the faculties that have not yet been purified. Rising in the east and sinking in the west: the east is azure and governs the liver, and the liver governs the eye; the west is white and governs the lungs, and the lungs govern the nose. This represents the arising of the merits of the eye faculty and the mutual extinction of the defilements of the nose faculty, as well as the arising of the merits of the nose faculty and the mutual extinction of the defilements in the eye. Rising and sinking in the other directions represent the arising and extinction of the other faculties in the same manner. As for the six movements: shaking, rising, surging, vibrating, roaring, and stirring. Within each one there are again three: namely, shaking, universal shaking, and equal universal shaking. Shaking directly is shaking; shaking of the four continents is universal shaking; shaking of the great trichiliocosm is equal universal shaking. The other five are also like this, totaling eighteen kinds of shaking; this precisely represents the purification of the eighteen realms (and so on).
