The ego is a tool artificially created by society to keep you on your toes, to let you run after shadows. The ego always trembles with fear, because it would die instantly if you realized that it was an artifact.
The ego is the cause of all problems, all conflicts, all wars, all fears, all jealousy and depression... because someone is better than you, more beautiful than you, smarter than you... it hurts so much. But these feelings only hurt because they hurt your ego. In this way, one wants to achieve more and more, to achieve more, to have more, to be more.... on the apparent way up in the material world of society. Recognize that it is not these things that hurt you, but that it only hurts your ego.
Let go of it and recognize the game of ego - the music will help you to do so.
