All negative thoughts — anger, fear, passion, compulsive craving — tend to be fast. If we could see the mind when it is caught in such thoughts, we would really see it racing. But positive thoughts like love, patience, tenderness, compassion, and understanding are slow — not turbulent, rushing brooks of thinking, so to speak but broad rivers that are calm, clear, and deep.
