"[One] very important aspect of loving kindness is learning to see the positive elements in us, to see the goodness in us, to see the Buddha nature in us. One way of being our own enemy is seeing only our mistakes, seeing only the negative things, only giving minuses to ourselves. So it is extremely important to learn to see the positive elements in us, it is very important to learn to give pluses to ourselves, learning to see our goodness, learning to see our Buddha nature in us. And when we learn to do this, what happens is we see the positive elements in others, we learn to give more and more pluses to others, we see more and more the Buddha nature in others, and then you come to a stage where you won't see a difference between yourself and others."
