One is the appointment of the Buddha’s two chief disciples Sariputta and Moggallana. It is said that Sariputta was appointed “Dharmasenadipathi” while Moggallana was named “Dharmapurohita”. Thereafter, the Buddha preaced the Anusaasana “Ovada Prathimoksha”, a teaching on self-discipline. The day also remembers the first-ever Buddhist Council where the Vinaya or code of fundamental ethics for the monks was proclaimed by the Buddha. On poya day, Buddhists clad in white will visit temples to observe Ata Sil (Eighth Precepts).
