大方廣佛華嚴經疏 55.30

55.30

九去不去者，末後二位無有辭去，以文殊無身顯離相故，普賢位極收盡法界故；餘皆辭去，學無常師，成勝進故。

Ninth, regarding taking leave or not taking leave: at the last two stations there is no taking leave and departing, because Mañjuśrī has no form, displaying transcendence of marks, and because Samantabhadra's station is ultimate, subsuming the entire dharmadhātu; at all the others he takes leave and departs, for learning has no fixed master, thereby effecting superior progress.
