As I was taking down my 2011 calendar which was entitled Rumi, Heart of the Beloved, I 
stopped to read the December poem/quotation I had not yet read. Here it is:
There is
nourishment like
bread that feeds
one part of your life
and nourishment
like light for
another.
There are many
rules about
restraint with
the former,
but only one rule
for the latter.
Never be satisfied.
Eat and drink the
soul substance, as
a wick does with
the oil it soaks in.
Give light to the
company.
