Byron Brown said this quote

[Self]-distrust manifests blatantly in the judge's reaction to your experiences of expansion. 'Expansion' here refers to situations when you try something new, success at something you're never done before, stop a self-destructive habit, speak up in your own defense, recognize a truth about yourself, take on a new responsibility, and so on. The expansion is a shift in your sense of who you are or who you have taken yourself to be: who you are becomes a little bigger, includes a little more than it did before.What does the judge do with these moments? Most everyone has experienced some sort of contraction after they expand: some letdown, some fear creeping in, some shame about being bigger, some withdrawal from the expansion. In one sense, this is part of a natural cycle of expansion and contraction. However, the contraction is seldom seen as part of the normal flow of the unfolding soul.
