Viceroy of Sena IV and probably his brother. He afterwards became king as Mahinda IV. (956-72 A.C.). He married a Kāliṅga princess. During his reign, the Vallabha king invaded Sri Lanka, but was defeated by the general Sena and entered into a treaty with Mahinda. Mahinda showed great favour to the Paṃsukulikas and the Lābhavāsins and decreed that the incomes derived from vihāras should not be taxed. His good acts were many. He had a Commentary to the Abhidhamma written by the Thera Dhammamitta in the Sitthagāma-pariveṇa and the Abhidhamma recited by the Thera Dāṭhānāga.

He made great offerings at the Mahā Thūpa and started to build the Candanapāsāda, where he had preserved the Hair Relic of the Buddha. He restored the temple of the four cetiyas in Padalañchana as well as the Temple of the Tooth, the Dhammasaṅganigeha and the Mahāpāli. He built the Mahāmallaka for the Theravāda nuns and completed the Maṇipāsāda. Mahinda’s wife was Kittī (q.v), who, herself, engaged in various works. Their son was Sena (Sena V). Cv.liv.1 ff; Cv.
