妙法蓮華經文句 2.4

2.4

本迹者，本住四無所畏，安住聖主如牛王第一義天；迹示牛呞樂居天上也。

In terms of the origin and traces: at the origin he abides in the four fearlessnesses, peacefully abiding in the holy lord like the Bull King in the heaven of the supreme truth; in traces he displays ox chewing and taking pleasure in dwelling in heaven.
