There is a ritual that we sometimes observe in Nichiren Shu called suigyo, or water purification practice. The phrases we recite as we are performing this ritual speak of cleansing ourselves, making our lives pure in order to carry out the practice of spreading the Dharma.
Let us renew our efforts to clean ourselves, not only physically but spiritually as well. Let us reconcile all of our past grudges, the things that hold us back, let us make fresh our entire lives, and renew our efforts to share the Dharma with great joy.
