The Sufi moral is this:
Love another and do not depend
upon his love; and: do good to another
and do not depend upon receiving good
from him; serve another and do not look
for service from him. All you do for another
out of your love and kindness, you should think
that you do, not to that person, but to God. And
if the person returns love for love, goodness
for goodness, service for service, so much
the better. If he does not return it, then
pity him for what he loses; for his
gain is much less than
his loss.
Do not look for thanks
or appreciation for all the good you do to
others, nor use it as a means to stimulate your vanity.
Do all that you consider good for the sake of
goodness, not even for a return
of that from God.
