Two thousand years ago Marcus Aurelius wrote:
"Our anger or annoyance are more detrimental to us than the things themselves which anger or annoy us".
Most of the time, you will find this to be true. Negativity strengthens the ego, but it weakens you. It prevents true intelligence from arising and dealing with situations and people. When you recognize its futility and harmfulness, it begins to subside. You can then face and accept situations and people as they are, without this unnecessary inner baggage. This is the beginning of wisdom in action.
