Some Eastern school philosophers believe that the Western sun or
“setting sun” is the path of the coward; however, this is not true...the Western sun, if not fully understood, is not the path of the coward, but can create the coward. For we must understand the principles of the Western sun, to confront the fears and evils of the world, and in order to embrace the Eastern sun, in order to embrace fear, we must first understand fear.
That fear is the Western sun; the Eastern sun is the way of being that helps us awaken to a greater sense of being and understanding.
Understanding both concepts allows us to embrace fear and live and accept your role in life; this is the concept of pu in Taoism. To become like an unworked piece of wood ready to be molded by the hand of the carpenter that is life; that is pu.
Understanding the Western and Eastern sun or rising and setting sun is key to achieving the understanding of Tao (Way), which guiding principles are that on yin and yang. This is key to attaining the principles of Wu-Wei (nonreaction), and becoming like a piece of pu (unworked piece of wood). Remember that we cannot fight life, instead we must embrace it and accept the path we are given; this is suffering.
Some things in life we can control, and others we must allow happen; these are the principles of Wu-wei, and Tao. The only way that we embrace these concepts is if we are able to achieve the Te, which are guiding virtues that we must have to able to embrace our path and achieve higher levels of enlightenment; this enlightenment is what we strive to achieve in Buddhism and Taoism.
