A competent and capable monk should inform those monks: ‘Please, venerables, I ask you to listen. Today is the observance day, the fifteenth. If the venerables are ready, we should do the observance-day ceremony by declaring purity to one another.’ The most senior monk should arrange his upper robe over one shoulder, squat on his heels, raise his joined palms, and say to the other monks: Please remember me as pure.’ And he should repeat this two more times. Each junior monk should arrange his upper robe over one shoulder, squat on his heels, raise his joined palms, and say to the other monks: ‘I’m pure, venerable. Please remember me as pure.’
