When a drop falls on the surface of still waters, concentric waves are formed. These waves always travel from the center toward the periphery —never in the opposite direction.
Similarly, when we cultivate spirituality, we start our practice of loving kindness and compassion with those beings closest to us.
If we can help to reduce the suffering and increase the happiness of our neighbor (in the strict sense of the word), gradually the circle of love and compassion will expand to encompass all beings.
