"...Shin Buddhism cautions us to always remember that, even if we do awaken to the Dharma and to our true, egocentric nature, we don't become "better people." We're still egotistical, judgmental, impatient, fallible and arrogant. In that sense, Buddhism is really beyond ethics, beyond "right and wrong," because it accepts, with compassion, that to be human is to be flawed. However, though we don't become "better" (more moral) people, we do gain insight. As mentioned above, what can change is the way we look at our lives and our relationship to others. We can come to see that our lives and, indeed, all life, is both interdependent and precious. This insight can have a profound and transforming effect on how we live our lives."
