The Uduwap Poya day, it is considered by Sri Lankan Buddhists to be of special significance because emperor Dharmasoka’s daughter, Theri Sanghamitta brought with her and her retinue a Bo-Sapling to Anuradhapura, from Buddha Gaya. It was on this day that the Bo-Sapling was ceremoniously planted at the Mahamewha Udyanaya and also the Sri Lanka Bhikkuni Sāsana was established when Queen Anula (reigned 47 BC – 42 BC) and other women entered the Bhikkhuni order.
