Quotes from Angulimala Sutra, Vol. 2
“Employing the analogies of empty settlements, depleted rivers, and waterless bottles, we can say that the so-called emptiness is empty because it lacks contents, not because there exist no containers (holders). The Tathagata denotes true liberation, and so does the notion of “non-empty”; it is called the emptiness of liberation because it denotes transcending all faults. The Tathagata is truly non-empty but devoid of all afflictions, celestial beings, and aggregates; thus, it is called the notion of emptiness.”
《央掘魔羅經》 卷2
「譬如空聚落，川竭瓶無水，非無彼諸器，中虛故名空；如來真解脫，不空亦如是，出離一切過，故說解脫空。如來實不空，離一切煩惱，及諸天人陰，是故說名空。」
