The abundant offering of the old woman was her giving all she had without expecting reward. I've never given all I have (actually the old woman gave very much but didn't give all she had). I see giving without expecting reward as the purest giving in that it is giving free and clear, not expecting anything in return, with no agenda, no manipulation, no expectation, no goal or purpose to be gained. When I have given without expecting any reward I feel most gratified. What helps me tap into my deepest abundance is reflection on what I have, awareness that I have a lot though really it's a gift and not mine, gratitude, openness of heart, and compassion.
