Stuck in my head...

On occasion, I get Hebrew prayers stuck in my head for no reason. I guess something about a tune and a string of syllables I know by heart but don't understand is conducive to popping into my head at random times. Anyway, my ramble on prayer is a whole 'nuther issue, but right now I have the Mi Shebeirach stuck in my head (the prayer for healing), specifically the version by Debbie Friedman, which is part in Hebrew and part in English. There are a couple English lines in there that are resonating with me right now:

May the source of strength who blessed the ones before us
Help us find the courage to make our lives a blessing
And let us say, Amen

I feel like it's a lot of what I'm feeling in Quaker Social Witness right now, of not knowing what I believe in (whether this source of strength is a "who" or not, for example), but knowing that I want to make a difference and live a good life. So may whatever has motivated and strengthened all those who came before me, give me the strength and courage to make my life a blessing as well.
