1. Udakadāyaka Thera. An arahant. In a
former birth he saw the Buddha Siddattha having his meal and brought him a pot
of water. Sixty-one kappas ago he became a king named Vimala (Ap.i.205). He is
probably identical with Sānu Thera. ThagA.i.115.
2. Udayadāyaka Thera. An arahant. In a
previous birth he filled a vessel of water for Padumuttara Buddha. As a result,
he could find water in any spot he wished (Ap.ii.437). His Apadāna-verses are
found in the Theragāthā Commentary under the names of two theras: Mahā Gavaccha
(i.57) and Gangātīriya (i.249).
