“Know that you possess the strong masculine principle [yang], yet abide by the meek feminine principle [yin]. Thus, become the flowing stream of the world.
As the flowing stream of the world, never swerve from your true nature. In this way, you return to the absolute integrity of a newborn babe.
Know the bright, yet keep to the dark. Never wavering from truth, you will conform to the pattern of an absolute being. In this way, you return again to the Infinite.
Know how to be honored and glorified, yet maintain unadorned plainness. Thus become the abundant valley of the world.
As the abundant valley of the world, you realize the sufficiency of the constant virtue of the universe. In this way, you return to the original simplicity of an uncarved block.
When the uncarved block is shaped into useful tools and vessels, its original qualities are destroyed. An absolute being, by preserving the original qualities, becomes the supreme ruler. This is called the great Oneness cannot be divided.”
