A teacup can only hold so much tea. If your cup is full, the tea will overflow on the table and will be wasted. If you have lost your teacup, the Tao itself will provide another. If you want to receive your fill of the teachings of the Tao, you must keep your cup empty, but do not be in a hurry to drink it. When drinking tea, drink tea, when walking, walk. Savor every moment, every drop of Tao.
