What is "pattini"

In Sinhala belief, Pattini (also spelled as Paththini) is a guardian deity of Sri Lanka. Goddess Pattini is worshiped by both Buddhists and Hindus and is the patron goddess of fertility and health - particularly protection against smallpox, which is referred to as deviyange ledé ('the divine affliction') in the Sinhala language. According to Sinhala mythology, the Bodhisattva Pattini was incarnated as Kannagi in order to rid the Pandya kingdom of its evil three-eyed king. She was said to have been born of a mango fruit, which was cut down by the god Sakra with an arrow.
