Pay no attention to the faults of others, things said or left unsaid by others, things done or left undone by others. Consider only what by oneself is said or left unsaid, done or left undone.
~ The real* Buddha

*At least three-quarters of the sayings you see posted on the Web and attributed to "Buddha" are treacly New Age verses with his title attached by someone who wanted to make it look more important. When you see an attribution here, it's taken from a direct translation of the Buddhist Canons or another reputable source. Same goes for The Dalai Lama.
