1.The universe is clear and bright. Since the furtive virtue of Heaven moves endlessly, not revealing its light, it exists forever. If Heaven does not conceal its virtue and reveal its brightness, the sun and the moon would not shine.

2. Evil qi, the Qpposite of vital qi, refers to all factors that cause one to fall ill. When evil qi takes control, the climate is stifled, earth becomes dark with clouds and fcg which do not lift. Rain will not fall and there is no communication between the earth and heaven.

3. Since yin and yang are not in harmony, no living creature is able to grow. Even large trees wither.
