Poson, held on the full moon day of June, commemorates the instance over 2,000 years ago when Arahat Mahinda, son of royal leader Asoka of India, converted King Devanampiyatissa to Buddhism. For Buddhists, this sacred day of Poson is next only to Wesak in terms of significance. Although Poson is celebrated throughout the island, the major ceremonies are to be found in Anuradhapura and Mihintale. Long lines of devotees dressed in white climb the many steps to the top of the Mihintale hill first to the temple, and then to the dagobas that lie adorn the nearby hillocks. In addition, many devotees climb to the very top of the rock, to the spot where Arahat Mahinda delivered his initial discourses.
