When you make people angry, they act in accordance with their baser instincts, often violently and irrationally. When you inspire people, they act in accordance with their higher instincts, sensibly and rationally. Also, anger is transient, whereas inspiration sometimes has a life-long effect.
There is a criterion by which you can judge whether the thoughts you are thinking and the things you are doing are right for you. The criterion is: Have they brought you inner peace?
Life’s like a mirror. Smile at it and it smiles back at you.
