Unitive knowledge is knowing by being: the knower is not set over against what is known but becomes one with it. The contemplative traditions speak of it as gnōsis, jñāna, maʿrifa, prajñā or the knowledge of God in the ground of the soul. It is contrasted with discursive knowledge, which proceeds by concepts, and is said to transform the one who knows.
