Look outward at the appearing objects, and like the water in a mirage, they are more delusive than delusion. Unreal like dreams and illusions, they resemble reflected moon and rainbows. Look inward at your own mind! It seems quite exciting, when not examined. But when examined, there is nothing to it. Appearing without being, it is nothing but empty. It cannot be identified saying, "that's it!" But is evanescent and elusive like mist. Look at whatever may appear in any of the ten directions. No matter how it may appear, the thing in itself, its very nature, is the sky-like nature of mind, beyond the projection and dissolution of thought and concept.
