ka dag: kadag, ཀ་དག་: alpha purity, original purity, primordial purity: “A Great Completion term meaning purity that is there from the first, that is, primordial purity. There are many terms in Buddhism that express the notion of “primordial purity” but this one is unique to the Great Completion teaching. The term “alpha purity” matches the Tibetan term both literally and in meaning.” Duff 2011
