On Binara Poya, Sri Lankan Buddhists commemorate the establishment of the Bhikkhuni Sasanaya (Bhikkhuni Sangha) or Order of the Female Buddhist Monastic. The very first bhikkuni ordained was the stepmother of Buddha, Mahapajapathi Gothami.
Mahapajapathi Gothami was the younger sister of Queen Maha Maya, the mother of Buddha. The Queen died a week after the birth of Buddha and the prince was raised by Mahapajapathi Gothami who subsequently married Buddha’s father King Suddodhana, becoming his stepmother.
The Vas season (Rainy-retreat) continues during the month of Binara, so the bhikkuni remain in their monasteries, engaged in meditation.
A highlight of Binara Poya is a Perahara (Procession) at Mahiyangana. The Veddah people (the indigenous people of Sri Lanka) are part of the procession and perform their own dance to mark the poya. The Mahiyangana Stupa was built to mark the location of Buddha’s first visit to Sri Lanka.
