Consciousness is everything

“Consciousness is everything. The world comes after consciousness; and it is here, in consciousness, that all the world is found to stand. From consciousness is all there is. One who knows self as consciousness has risen, from the seeming world, to this unconditioned state where everything is only light. Here, all desires are attained, and deathlessness is realized.” (Aitareya Upanishad III 1, 3-4)
