This transformation expresses the boundless compassion, nonjudgmental and all-inclusive, that is the moving force in the Buddhist tradition. It is not, however, a simple, naive optimism, for the starting point of Buddhism is a recognition of the universal fact of human suffering, born of both personal and collective karma. In fact, it is a realistic appraisal of life as it is, not merely on the surface of things but at its most profound depth. In this depth, abundant with the accumulated pain and sorrow of humanity, is also found the capacity of the human spirit to achieve its fullest potential, no matter the obstacles, through awakening to the working of boundless compassion deep within our life.
