the belief of "I don't deserve"

Doc wrote in Letting Go, pg. 112:

"Other blocks to the achievement of our wants and desires, of course, are unconscious guilt and smallness. Peculiarly, the unconscious will allow us to have only what we think we deserve. The more we hang on to our negativity and the small self-image that results, the less we think we deserve, and we unconsciously deny ourselves the abundance which flows so easily to others."
