You will better love yourself (and others). Have higher self-esteem. Be kinder to yourself and others. Spend less time hiding your true self. Live with less fear, worry, trying to please others, and live up to the expectations of others. You will believe the truth about yourself, and not lies. You will have more empathy for yourself and others. You will see yourself more accurately, the good and bad parts, and still love yourself and enjoy yourself.
It does not mean we will never feel the emotions of shame again, but we will have the tools to deal with these emotions and painful experiences that are causing us shame and ultimately shame will not be able to grow and bury itself within us.
