Sometimes you have a flash of insight, but it's not strong enough to survive. Therefore in the practice of Buddhism, samadhi is the power to maintain insight alive in every moment, so that every speech, every word, every act will bear the nature of that insight. It is a question of cleaning. And you clean better if you are surrounded by those who are practicing exactly the same.
Nhat HanhAnger is like a storm rising up from the bottom of your consciousness. When you feel it coming, turn your focus to your breath. Breathe in deeply to bring your mind home to your body. Then look at, or think of, the person triggering this emotion: with mindfulness, you can see that they are unhappy and suffering. You can see their wrong perceptions. You'll feel motivated by a desire to say or do something to help the other person suffer less. This means compassionate energy has been born in your heart. And when compassion appears, anger is deleted.
