大方廣佛華嚴經隨疏演義鈔 60.123

60.123

疏「彼四地之慧」下，揀今修慧但是四地證前相故。尋求趣本，故名彼慧以為光明，由此三地得名明地。

Regarding the commentary's passage from "The wisdom of that fourth stage..." onward: this distinguishes the present wisdom of cultivation as merely being the prior sign of realization of the fourth stage. Seeking and proceeding toward the source, that wisdom is therefore called "radiance"; because of this, the third stage receives the name Ground of Radiance (Prabhākarī).
