In my experience, my belief systems have been, and are, like the shell of an egg. Without its shell, a chick would be an amorphous blob and would die. Like the shell, our old belief systems gave us direction, form, and protection when it was needed. The time comes, however, when the chick grows too big for the shell. At that time, the shell ends its role of being life-giving. Its last beneficial role is to become something that the chick has to struggle against, giving the chick life and definition. In fact, if one helps the chick out of the shell so that it has no struggle, it will die.
In the same way, the struggle of “breaking out of the shell” of our old beliefs helps us to define ourselves and propels us forward. Although our new beliefs give us wonderful room to grow when we first break out of the shell, it is wonderfully humbling and freeing to remember that even these new beliefs will one day be outgrown. Remembering this can help to keep us from judging the beliefs of others - reminding us that no one and no one’s beliefs are better than any other. They are simply a preference that may fit us better at this time. In fact, that we sometimes create situations that are painful does not mean we are evil or stupid. It simply means that we are fully free to explore while we go on the journey of remembering who we truly are.
