When we can laugh at our character defects, rather than find them embarassing or shameful, we have reached a jumping-off place in our spiritual growth. If we have the faith and trust to take the leap, we will be amazed to discover how joyful everyday life can be.
I asked my HP to remove the awful judgemental attitude I had towards other people, but first I'd had to ask to have that same judgement about myself removed. When I stopped condemning myself for my human frailties, I was moving towards a state of mind that was incomprehensible to me before then. I did not know, believe, or even dimly understand that I would feel my HP's love for me, and through that, find my own love for myself. I did as I was instructed by Al-Anon and my sponsor, and reaped rewards far beyond what I was able to imagine at the time.
We don't have to believe it will work, in order for it to work, we have only to try it and see. I don't need to understand gravity in order for my physical self to be governed by it. In the same way, I don't need to understand 12-Step principles in order for my life to be immeasurably enriched by them, if only I practise them. The understanding, the belief, that comes later. You'll never know if you don't try.
Give it a whirl - time is passing either way.
