Tao is the source of both fullness and emptiness. But it is itself neither fullness nor emptiness.
ZhuangziMan may rest in the eternal fitness; he may abide in the everlasting; and roam from the beginning to the end of all creation. He may bring his nature to a condition of ONE, he may nourish his strength; he may harmonise his virtue, and so put himself into partnership with God.
ZhuangziHow do I know that loving life is not a delusion? How do I know that in hating death I am not like a man who, having left home in his youth, has forgotten the way back?
ZhuangziThere is danger for the eye in seeing too clearly, danger for the ear in hearing too sharply and danger to the heart from caring too greatly.
