首楞嚴義疏注經 9.38

9.38

前雖徹意地樂，止在身心未名為遍；今則遍於依正，樂淨圓融，世界、身心無處不遍，殊勝妙樂以成淨德。言勝託者，即此淨樂，是彼行者所依勝處，證此樂故名之為歸。

Although previously bliss pervaded the ground of mind, it was limited to body and mind and was not yet called pervasive; now it pervades both circumstantial and direct retributions, bliss and purity being harmonious and complete, with no place in the world, body, or mind not pervaded; exquisite and wondrous bliss accomplishes pure virtue. The "superior refuge" is this very pure bliss, which is the superior place upon which those practitioners rely; because they realize this bliss, it is called "returning."
