Everything in life changes. The path to true happiness is one of integrating and fully accepting all aspects of our experience. This integration is represented in the Taoist symbol of yin/yang, a circle which is half dark and half light. In the midst of the dark area is a spot of light, and in the midst of the light area is a spot of darkness. Even in the depths of darkness, the light is implicit. Even in the heart of light, the dark is understood, acknowledged, and absorbed. If things are not going well for us in life and we are suffering, we are not defeated by the pain or closed off to the light. If things are going well and we are happy, we are not defensively trying to deny the possibility of suffering.
