Experienced meditators describe how in meditation, as the mind begins to still and the voice in the head speaks less frequently, there is often a rush of thoughts that are most important to sustaining the self-image. This is how meditators can notice what mental stories and thought patterns are their most prevalent preoccupations, as the mind reverts to replaying these topics as a defense against slowing down. Some Eastern teachers explain that the mind “keeps talking” in this way because it's the only way it can exist.
