八大在我

The eight great powers of personality or sovereign independence, as one of the four qualities 常樂我淨 of nirvāṇa: powers of self-manifolding, infinite expansion, levitation and transportation, manifesting countless forms permanently in one and the same place, use of one physical organ in place of another, obtaining all things as if nothing, expounding a stanza through countless kalpas, ability to traverse the solid as space. v. 涅槃經 23.
