Becoming, which results from clinging, involves the idea of having or being something more satisfying than at present. We want to become a very good meditator, or we want to become spiritual, or more learned. We have all sorts of ideas but are all bound up with wanting to become, because we are not satisfied with what we are. Often we do not even pay attention to what we are now, but just know that something is lacking. Instead of trying to realize what we are and investigating where the difficulty actually lies, we just dream of becoming something else. When we have become something or someone else, we can be just as dissatisfied as before.
