Understanding Poya Days

Buddhists use these days to reflect, meditate, observe precepts, make offerings, and reconnect with their spiritual goals.

Unduvap Poya is the twelfth and last Poya of the year, symbolizing completion, maturity, and the continuation of the Buddhist legacy. Among all Poya days, it stands out for a reason that touches the heart of every Buddhist: the arrival of Sangamitta Theri with the sacred Bodhi tree sapling.
What Is Unduvap Poya?
Unduvap Poya falls in December each year according to the lunar calendar. Its importance comes from one of the most emotional historical events in Sri Lankan Buddhism. On this day, more than two thousand years ago, Sangamitta Theri arrived in Sri Lanka bringing the southern sapling of the original Sri Maha Bodhi tree from India. This is the very tree under which the Buddha attained Enlightenment.
The arrival and planting of this sapling carried spiritual, cultural, and political meaning. It shaped Sri Lankan civilization in a powerful way. To this day, this Bodhi Tree is the oldest historically documented, human-planted tree in the world. It still grows with thousands of devotees visiting it every month.
The Story Behind Unduvap Poya
Who Was Sangamitta Theri?
Sangamitta Theri was the daughter of Emperor Ashoka and the sister of Arahant Mahinda Thera. She was ordained as a Buddhist nun and dedicated her life to spreading the Dhamma. When Sri Lanka embraced Buddhism through Mahinda Thera, King Devanampiyatissa requested the establishment of the female order as well, so that women could also enter the Sangha.
Sangamitta Theri responded to this request with compassion and wisdom. She sailed from India to Sri Lanka carrying not only the sacred Bodhi sapling but also the knowledge and discipline required to establish the Bhikkhuni Order.
Her Journey Across the Sea
The journey from India to Sri Lanka was not simple. It required courage, devotion, and a deep sense of purpose. According to the chronicles, Sangamitta traveled across the ocean with monks, artisans, and attendants. The vessel carried the precious southern branch of the Bodhi Tree, carefully protected as a supreme relic.
The ship arrived on Unduvap Full Moon Poya Day in the ancient port of Jambukola. The moment she stepped onto Sri Lankan soil is celebrated as a turning point in the island’s spiritual history.
The Arrival of the Sacred Bodhi Sapling
King Devanampiyatissa welcomed Sangamitta Theri with great honor. The sacred sapling was received with royal and spiritual ceremony. The Mahavamsa describes the procession as one filled with joy, devotion, music, flowers, and blessings.
The sapling was carried in an elaborate procession to Anuradhapura. At Mahamevnawa Gardens, it was planted in a specially prepared terrace. This location later became one of the most sacred spaces in Sri Lanka.
The sapling grew into the Jaya Sri Maha Bodhi, a living symbol of peace, compassion, and enlightenment.
The Oldest Living Sacred Tree in the World
The Jaya Sri Maha Bodhi is unique because:
For millions of Buddhists, offering flowers, lighting lamps, and meditating under the shade of this sacred tree brings immense merit and inner peace.
Unduvap Poya and the Bhikkhuni Order
Unduvap Poya also marks the establishment of the Bhikkhuni Sasana in Sri Lanka. Sangamitta Theri ordained the first group of Sri Lankan women, including Queen Anula, giving them the opportunity to become nuns and follow the path of liberation.
This event is extremely important for gender equality in early Buddhist history. It demonstrates that Buddhism embraced the spiritual potential of women more than two thousand years ago.
Many modern Buddhist women still honor Sangamitta Theri on Unduvap Poya as their spiritual mother and guide.
