A monk of Kutumbiya Vihára. Having heard the Satipatthána Sutta from Tissa Thera of Ambalena, he was on his way back when he met a wild elephant. By his virtue the elephant was subdued and Tissamahánága took shelter from a storm under the elephant's body. There he developed arahantship. He then went to Viyolaka-Vihára with the elephant, and for thirty years the animal waited on him.
After death the monk's remains were cremated at Kutumbiya Vihára, and the elephant participated in the celebrations. Ras.ii.185f.
