From ancient times, people who knew the heavenly law realized that the basis of life is rooted in the yin and yang. Between the heaven and earth and in the six orientations, the nine states, the nine orifices, five zang-organs and twelve joints all correspond to the qi of yin and yang of nature, which yields the five elements and the three yins and three yangs. If the numbers infringe these (five or three), the evils will impair people. The yin and yang are the basis of life.
