Unduvap Full Moon Poya Hero

Sangamitta Theri

Sangamitta Theri, daughter of Emperor Ashoka of India, was a Buddhist nun who played a pivotal role in spreading Buddhism to Sri Lanka. In the 3rd century BCE, she traveled to the island, carrying a sapling from the sacred Bodhi tree under which Buddha attained enlightenment. Her arrival on Unduvap Poya Day marked the establishment of the Bhikkhuni (female monastic) order in Sri Lanka and significantly deepened the roots of Buddhism there.

History of Unduvap Full Moon Poya

This public holiday in Sri Lanka celebrates the arrival of the Bo tree sapling in Anuradhapura, which was brought by Ashoka’s daughter, Sangamitta. History states that Lord Buddha attained enlightenment by meditating under a Bodhi tree in Bihar, India. Years later, Sangamitta, along with several members of the royal family, entered the Sasanaya in Dambakolapatuna Port in Jaffna on an Unduvap Poya day. The sacred Bo sapling was brought to Sri Lanka in a golden bowl and thereafter planted in the Mahamewna Garden in Anuradhapura. Bo saplings from this tree were taken to other parts of the island to spread the Buddhist philosophy and culture.

Moreover, Sangamitta has also spread her diverse skills in crafts and disciplines, such as woodwork, agriculture, indigenous medicine, etc., which helped in the development of the country. On this day, every year, Buddhist devotees flock to Anuradhapura in thousands on Unduvap Full Moon Poya day to pay homage to the sacred Bo tree. It is also said that Lord Buddha visited Sri Lanka during his lifetime. Today, the most sacred tree in the world is the JayaSri Maha Bodhi Standing at Mahamevna Uyana.

In Sri Lanka, every full moon day is a public holiday and each of these days has its own name and commemorates key events in Buddhism. These full moon days or Poya will change each year and on these days, shops and businesses will usually remain closed and the sale of meat and alcohol is forbidden.
