Pure Knowledge does not contain objects in it nor reflect objects.

Ramana Maharishi:  Pure ether cannot take reflections; only the ether of water can do so. Glass cannot reflect objects; only a plate of glass with an opaque lining on its back can reflect the objects in front of it. Similarly Pure Knowledge does not contain objects in it nor reflect objects. Only with the limiting adjunct, the mind, it reflects the world. Neither in samadhi nor in deep sleep does the world remain. There cannot be illusion either in bright light or in total darkness. Only in dim light a rope seems a snake. Similarly Pure Consciousness remains light only; it is pure knowledge. The mind rising from it is deluded that the objects remain apart.
