首楞嚴義疏注經 6.395

6.395

「若諸比丘不服東方絲綿絹帛，及是此土靴履裘毳、乳酪醍醐。如是比丘於世真脫，酬還宿債，不遊三界。」

"If monks do not wear silk, floss, fine silk, or gossamer from the east, as well as boots, shoes, furs, and down from this land, or consume milk, curds, or clarified butter, such monks are truly liberated from the world. Having paid back their past debts, they will not wander through the three realms."
