There are three layers to the universe. In the lower, Tai Ching, and the middle, Shan Ching, the hindrance of a physical bodily existence is required. Those who fail to live consistently in accord with the Tao reside here. In the upper, Yu Ching, there is only Tao: the bondage of form is broken, and the only thing existing is the exquisite energy dance of the immortal divine beings.
LaoziShe who is centered in the Tao can go where she wishes, without danger. She perceives the universal harmony, even amid great pain, because she has found peace in her heart. Music or the smell of good cooking may make people stop and enjoy. But words that point to the Tao seem monotonous and without flavor. When you look for it, there is nothing to see. When you listen for it, there is nothing to hear. When you use it, it is inexhaustible.
LaoziIf you realize that all things change, there is nothing you will try to hold on to. If you are not afraid of dying, there is nothing you cannot achieve
LaoziOnce you arrive {at a spontaneous awareness of the Great Oneness}, remember: it isn't necessary to struggle to maintain unity with it. All you have to do is participate in it.
Laozi
