We are happy when we are in harmony; according to the Tao Te Chingi, in harmony with the Tao. The Tao is the Way – essentially, the natural flow of the universe and how it operates. It is an impersonal force according to the Tao Te Ching, but there is no problem in calling this ‘God’ if one wishes to. The point is that the universe conforms and complies with certain rules and principles and when we violate these we suffer.
