妙法蓮華經文句 2.108

2.108

本迹者，十住、行、向即三十，十地為一，等覺為二，妙覺為主，同棲第一義天，共服實相甘露即本也，居須彌頂迹也。

As for the origin and traces: the ten abodes, practices, and dedications are thirty; the ten stages make one; equal awakening makes two; and wondrous awakening is the lord. Dwelling together in the Heaven of the Supreme Truth, and jointly tasting the ambrosia of true reality, is the origin. Residing atop Mount Sumeru is the trace.
