All that is limited by form, semblance, sound, color is called object. Among them all, man alone is more than an object. Though, like objects, he has form and semblance, He is not limited to form. He is more. He can attain to formlessness. When he is beyond form and semblance, beyond "this" and "that," where is the comparison with another object? Where is the conflict? What can stand in his way? He will rest in his eternal place which is no-place. He will be hidden in his own unfathomable secret. His nature sinks to its root in the One. His vitality, his power hide in secret Tao.
ZhuangziWhen you're dreaming, you don't know it's a dream. You might even interpret a dream in your dream - and then wake up and realize it was all a dream. Perhaps a great awakening will reveal this to be a dream as well.
