One who is in harmony with the TAO is like a newborn child: full of vitality, virility, natural, without fear, not knowing danger, protected, safe from insects, snakes, beasts, and birds of prey. A baby's bones are soft and its muscles are weak, but its grip is firm. It doesn't know about the union of male and female, yet its sex organs are active. So intense is its vital power. It can scream its head off all day, yet it never becomes hoarse, so connected is its life force. The TAOists` power is like this. They let things come and go; effortlessly, without desire. They never expect results, and thus they're never disappointed, and their spirit never grows old. To know harmony is to know the eternal; to know the eternal is to have insight. To improve upon life is ominous. To control the life breath (ch`i) by the mind is aggressiveness, or being forceful. When one is too aggressive, things decay. This is non-TAO. Non-TAO soon ends. To know TAO is to know harmony, to know the changeless, the eternal, everlasting, the constant. This brings insight, intuition, and illumination.
