A special fasting and purification practice performed in conjunction with Eleven-faced (or Thousand-armed) Avalokiteshvara. This is a very powerful method for purifying negativities of body, speech and mind, and for pacifying strong delusions such as desirous attachment and hatred. It is also a special way of receiving blessings and for improving our minds of love, compassion and bodhichitta. This practice is done annually at Kadampa Buddhist centres throughout the world in a two-day retreat – called the Nyungnay Purifying Ritual Practice – to celebrate Buddha’s Enlightenment Day.
