Poson Poya is second only in importance to Vesak and commemorates the introduction of Buddhism to Sri Lanka by the Buddhist missionary monk Mahinda in the 3rd century B.C.
Mahinda met King Devanampiyatissa at Mihintale, a mountain peak near Anuradhapura in Sri Lanka, and preached the first sermon. This is why Mihintale is often called ‘the cradle of Buddhism’ in Sri Lanka.
Although Poson is celebrated across Sri Lanka, the main event is a mass pilgrimage to Anuradhapura, while thousands of white-robed pilgrims climb to the summit of Mihintale to the spot where Mahinda gave his first sermon.
Poson is a very religious festival and temples on the island are filled with devotees and pilgrims to mark this great event. Others may perform religious activities like reading holy books or listen to monks tell stories about Buddha’s life.
During the Poson Festival, the selling of alcohol and meat is usually prohibited.
