Conciousness as mirror.
''Though conciousness is all-pervading, dense and single, it still holds the mobile and immobile creation within it, wonderful in its variety, with no immediate or ultimate cause for it. Just as the mirror remains unaffected by the passage of different images and yet continues to reflect as clearly as before, so also the one conciousness illumines the waking and dream states which can be verified by proper meditation. ''
