I’d say even more than part of our lives, it seems to be our whole idea of living!
We build an image of ourselves and others, of how things “should” be, and then live from those ideas. Furthermore, imagery goes as far down as consciousness itself.
There can’t be an idea without a goal, an expectation. Our idea of love is based completely on expectations and sensations. Our idea of how a country should be run, is based on our immediate life experiences. Our idea of a cloud or tree is dependent on how we view the world around us. The list goes on and on…
Our idea of truth also seems to be complex, but it is really the most simple thing. The problem is that the complexity of our attachments get in the way.
We fall into what is easiest. It’s hard to see the simplicity of awareness, but easy to keep believing the same illusions.
