Hmmm... well, here goes. To me, the "management" of great qualities means the productive use of them. "Great qualities" would include love, integrity, reliability, honesty, loyalty, kindness, equanimity, open-mindedness, faith, confidence and joy. Productive use of these is employing each as a natural part of daily living, in all situations and relationships. This quote is a fancy way of saying "walk the walk, don't just talk the talk."
Lately I've been adding to my prayers, "Use me." I know I can count on Spirit to do that. I don't know what form my next usefulness will take, but I can count on Spirit finding a joyful way to use my great qualities, based on past experience. Spiritual "nudges" have led me into great adventures of love, learning and usefulness.
Happy to be here,
