In the heart that harbors the weed of selfish greed, the flower of love cannot survive.
Love is a state of complete, uninhibited, unconditional giving away of every aspect of our very existence for the pleasure of the object of our love, both within and without.
Real love is expressed through service. A mother is willing to do anything and everything to serve the child. She is willing to stay up late in the night, willing to clean all the mess that the child creates and willing to sacrifice her very life for the child. That is service.
Success of our activites is when we have absorption in God.
