Tom: Practicing acceptance is a powerful teaching, but ultimately if you think this is about accepting or not-resisting, then you are identified with the body-mind entity, as it is the mind that accepts or resists.
See this: acceptance and resistance are both objects that appear spontaneously to you. There is no need to change anything, no need to accept or reject, no need to imagine there is a separate doer-self there.
What is, is. Simple.
