Complaining is one of the ego's favourite strategies for strengthening itself. Every complaint is a little story the mind makes up that you completely believe in. Whether you complain aloud or only in thought makes no difference... Instead of overlooking the unconsciousness in others, you make it into their identity. Who is doing that? The unconsciousness in you, the ego. Sometimes the "fault" you perceive in the other person isn't even there. it is a total misperception, a projection by the mind conditioned to see enemies and to make itself right and superior. At other times, the fault maybe there but by focusing on it, sometimes to the exclusion of everything else, you amplify it. And what you react to in another, you strengthen in yourself.

See if you can catch yourself complaining in either speech or thought, about a situation you find yourself in, what other people do or say, your surroundings, y...our life situation, even the weather. To complain is always nonacceptance of what is. It invariably carries an unconscious negative charge. When you complain, you make yourself a victim. Leave the situation or accept it. All else is madness.Eckhart Tolle
