Without an inside, without an outside, awareness arisen of itself, as wide as the sky, beyond size, beyond direction, beyond limits - This utter, complete openness: Space, inseparable from awareness. Within that birthless, wide-open expanse of space, phenomena appear - like rainbows, utterly transparent. Pure and impure realms, Buddhas and sentient beings, are seen, brilliant and distinct.
