Observed by Buddhists in Sri Lanka, this day celebrates the arrival of Sanghamita, daughter of Emperor Asoka of India, in 288 BCE. According to legend, Buddhism was first brought to Sri Lanka by a group of missionaries led by Mahinda, Asoka’s son. Mahinda later sent for his sister, Sanghamita, who arrived with a branch from the Bodhi tree at Gaya, sacred to Buddhists as the tree under which the Buddha was sitting when he attained Enlightenment. The sapling was planted in the royal city of Anuradhapura, where Sanghamita founded an order of nuns. Discuss
