To overcome ego, we have to undo our habitual patterns, which we have been developing for thousands of years, thousands of aeons, up to this point. Such habitual patterns may not have any realistic ground, but nonetheless, we have been accustomed to their dirty work, so to speak. We are used to our habitual patterns and neuroses. We have been used to them for such a long time that we end up believing they are the real thing. To overcome that, we have to see our egolessness, how we can actually overcome our anxiety and pain. In Buddhist terms this is known as liberation, freedom from anxiety, and nirvana, or relief.
