法華遊意 1.218

1.218

二者、白是眾色之中本，明一乘為三乘之本，故於此一說三；說三為一，令歸於一法身。一法身垂於應迹說於應用，為令悟於法身，故初章以一乘為本。次段以法身為本，欲顯二本之義，故以本色為名。三者、駕御大車即是白牛，白牛喻平等大慧，無有漏之垢故秤為白。此經文雖七軸宗歸大慧，故舉白牛為喻也。

Second, white is the root among all colors, clarifying that the ekayāna is the root of the triyāna; therefore, based on this one [vehicle], three are spoken of, and three are spoken of as one to cause them to return to the single dharmakāya. The single dharmakāya manifests trace-responses to speak of responsive functions, in order to make them awaken to the dharmakāya; therefore, the first section takes the ekayāna as the root, and the second section takes the dharmakāya as the root. Desiring to reveal the meaning of these two roots, it takes the root color as its name. Third, driving the great cart refers to the white ox; the white ox symbolizes equal great wisdom, and because it is devoid of the defilement of the āsravas, it is called white. Although the text of this sūtra spans seven fascicles, its overarching principle returns to great wisdom; therefore, the white ox is cited as a metaphor.
