Patience does not mean biding your time and trying to slow down. Impatience arises when you become too sensitive and you don’t have any way to deal with your environment, your atmosphere. You feel very touchy, very sensitive. So patience is often described as a suit of armor. Patience has a sense of dignity and forbearance. You are not so easily disturbed by the world’s aggression.
