Ego

The person, the individual, the ego, is but an object of perception, it is only habit or error that we identify ourselves with our perceptions and this is itself the cause of all our suffering. - Jean Klein

If you want to reach a state of bliss, then go beyond your ego and the internal dialogue. Make a decision to relinquish the need to control, the need to be approved, and the need to judge. Those are the three things the ego is doing all the time. It's very important to be aware of them every time they come up. - Deepak Chopra
