A Paribbājaka. He once visited the Buddha at Veḷuvana and questioned him regarding predestination. The Buddha explains to him that suffering arises from various causes—bile, phlegm, wind, bodily humour, change of season, stress of untoward happenings, sudden attacks from without and also from one’s kamma—and to say that these are all predestined is to go too far. Sīvaka expresses his approval and declares himself the Buddha’s follower. SN.iv.230f. Another conversation he had with the Buddha is recorded in the Aṅguttara Nikāya. AN.iii.356 There he asks the Buddha if the claims made with regard to the Dhamma are justified. The Buddha proves to him, by illustration, that they are.
