# Great Okay a coined term denoting the hypothetical proposition of a total acknowledgment which, when given, would cause everything (i.e. the entire physical universe) to vanish. "Great Okay" is a humorous take-off on "great Amen," an expression used in a poem (and later a song with the same lyrics) A Lost Chord, by Adelaide Anne Procter (1825-1864). The poem is about a troubled person who, while idly playing the organ, accidentally strikes a beautiful chord which brings calm and quiets her troubles. "But I struck one chord of music like the sound of a great Amen." She searches again for the chord but can't find it, and thinks that perhaps she will hear it again at death.
