He was a householder of Sāvatthi and had a son called Sigālaka. Later he entered the Order, and the Buddha asked him to meditate on the idea of a skeleton. He lived in the Bhesakalāvana in Sumsumāragiri, and there a woodland sprite once encouraged him with a verse (Thag.vs.18). Thus, urged to strive, he developed insight and became an arahant.
Ninety four kappas ago he had given a tāla fruit to the Pacceka Buddha Sataramsī. In the time of Kassapa Buddha he was a monk and developed meditation on the idea of a skeleton. ThagA.i.70f.
