The rains retreat ends; the Kathina season of gifts of robes begins. Pavāraṇā (Pali; Sanskrit: Pravāraṇā) is a Buddhist ceremony held on Aashvin full moon of the lunar month. This usually occurs on the full moon of the 11th month. It marks the end of the three lunar months of Vassa, sometimes called "Buddhist Lent." The ceremony is marked in some Asian countries where Theravada Buddhism is practiced. On this day, each monk (Pali: bhikkhu) must come before the community of monks (Sangha) and atone for an offense he may have committed during the Vassa. Mahayana Buddhists also observe Vassa, many Son/Thien monks in Korea and Vietnam observe an equivalent retreat of three months of intensive practice in one location.
