"Emotions come from frustration. The meaning of emotion is frustration in the sense that we are or might be unable to fulfill what we want. We discover our possible failure as something pathetic, and so we develop our tentacles or sharpen our claws to the extreme. The emotion is a way of competing with the projection. That is the mechanism of emotion. The whole point is that the projections have been our own manifestations all along."

~Chogyam Trungpa Rinpoche
