A monk of Asiggāhaka-pariveṇa. One day, after having obtained alms in Candavaṅkavīthi, he fed a starving bitch. That same evening he got large quantities of ghee and molasses which he gave to his colleagues. For thirty-two years he gave alms to thousands of monks from food given to him by the people of Candavaṅkavīthi. Later, he became an Arahant. Once, 500 monks on pilgrimage to the Bodhi-tree, took him with them to avert danger. In four months they reached Koṭṭapaṭṭana and in seven months the Bodhi-tree, being well entertained everywhere. On the way back Cūḷanāga was seized with a colic and died; but before death he advised his colleagues to cremate his body and take his ashes that they might be provided with their wants. Ras.ii.122 f.
