Tissa Mahā Nāga Thera untranslated

Tissa Mahā Nāga Thera. A monk of Kuṭumbiyavihāra. Having heard the Satipaṭṭhānasutta 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 Tissa Mahā Nāga took shelter from a storm under the elephant’s body. There he developed Arahant-ship. He then went to Viyolakavihāra with the elephant, and for thirty years the animal waited on him.

After death the monk’s remains were cremated at Kuṭumbiyavihāra, and the elephant participated in the celebrations. Ras.ii.185f.
