“I am not angry with you,” he says to the painful feeling, because he does not perceive it as bad or harmful. It enters the mind in the age-old manner, through sensation, a natural physiological process that humans share with animals. Ironically, you don’t need to try to suppress or resist unpleasant feelings as long as you abandon the belief that they are bad. If you accept them with indifference, then they do you no harm.
