The world is made only of seeing, hearing, touching, tasting and smelling. Let us call these, perceiving.
Perceiving is made of mind and mind is made of Consciousness.
Consciousness has no colour of its own and as the world (that is, perceiving) is only made out of this colourless Presence, it is sometimes referred to as being transparent.
Consciousness is the light that illumines all experience and as there is no other substance to our experience of the world other than this luminous Consciousness, the world is known to be luminous, made out of the light of Knowing.
Consciousness illumines the apparent world and its light is also the substance of that which it illumines and knows. In other words, the Knowing of the world and the Existence of the world are made out of the same transparent, luminous stuff.
