Special ceremonies, rituals and devotional practices are observed at the Rajbana Vihāra in order to understand and follow the Buddha’s teachings and doctrines, and simultaneously acquire merits (puññā). These Dhammika events are not characterized by Dhammika psychology such as solemn environment rather they bridge friendship among social beings through love, compassion, and affection. Besides, the festive environment remove the ignorance, impatience and cruel tendencies human have hidden inside their minds, at least for a few moments by practicing precepts and veneration to the Buddha.

The following events are performed on some full moon days at the Rajbana Vihāra.

  1. The Baishakhi Full Moon Day: This day is also called the Buddha Full Moon Day which commemorates the events of the Buddha’s birth, enlightenment, and Nibbāna.

  3. The Bhadra Full Moon Day: It is prominently known as the Madhu (Honey) Full Moon Day. The day is remembered for the offering (Dāna) of a honeycomb to the Buddha by a monkey.
