Summary: Perception of reality is the basis of the self's experience of reality. One can pollute the self by perceiving ones realities from a negative or pessimistic position, but to ignore the reality of negativity is to damage (partially blind) oneself to the truth of reality. The one who sees the complete truth is one who looks upon the world with eyes completely open to all. Look upon the "sinners" and the "saints" equally, and look upon the "neutral" ones equally as well. See the light and the darkness as one, and everything between. Know all things possible. Knowing begets knowing, learning begets learning, truth begets truth.

I apologize if that sounded too biblical, but it was the easiest way to express that opinion, given that the language I am communicating in is riddled with religion/spirituality. Try to see the meaning past the words and accept or reject it on its core value. This is another truth.
