Professor Raimundo Panikkar, The Vedic Experience

 This is the supreme light spoken of in the Rig Veda and in the Brahmanas; it is mentioned also in the Chandogya Upanishad and in the well-known prayer of the Brihadaranyaka Upanishad: "Lead me from darkness to light!" It is also the refulgent light of the golden vessel stationed in the dwelling place of the Divine: "The impregnable stronghold of the Gods has eight circles and nine gates. It contains a golden vessel, turned toward heaven and suffused with light.” This light is neither exclusively divine nor exclusively human, neither merely material nor merely spiritual, neither from this side only nor from the other. It is precisely this fact that "links the two shores.” This light is cosmic as well as transcosmic.”
