Where did the ego come from?
Does the world manifest material complexity outwards, resulting in subtler layers of existence? Does it start from insentient matter which then becomes biological life that develops into sophisticated beings with specific senses, ego and finally this consciousness now reading these words while thinking I am reading? This sequence of unfolding is what we are told is true. But have you investigated it?
We are looking for something that we can add to our lives. Something that can give us the feeling of being safe, of being valuable, loved, and peaceful, and everyone has a, perhaps subconscious, idea of how it will feel or look when the goal is reached or fulfilled. When everything falls in to place.
What it is we think we should achieve depends on what we define ourselves as, and what we define ourselves as defines our idea of success.
