It is vital to actively manage ones ego if one is to live a happy and healthy life!
Many people identify with their ego. In other words, they believe they are the ego. When one identifies entirely with ones ego, ones connection to the World and the people in it becomes purely physical and mental and a grave sense that fundamental meaning is missing in ones life is the result. Conversely, when you realise that your mind and body are merely temporary possessions and yet understand that there is far more to you, you will feel an inevitable sense of peace and acceptance.
As you encourage your ego to release unnecessary preoccupations, you will surely begin to rediscover yourself.
