Buddhism is a path of supreme optimism, for one of its basic tenets is that no human life or experience is to be wasted, abandoned, or forgotten, but all should be transformed into a source of vibrant life, deep wisdom and compassionate living. This is the connotation of the classical statement that sums up the goal of Buddhist life: "Transform delusion into enlightenment." On the everyday level of experience, Shin Buddhists speak of this transformation as "bits of rubble turned into gold."
