A very learned brahmin of Candalakappa. One day he saw Dhānañjānī trip up, and heard her exclaim three times, “Glory to the Buddha, the arahant, the all enlightened.” He blamed her for thus extolling a shovelling monk, but when she told him of the Buddha’s marvellous qualities, he felt a desire to see him. Some time after, the Buddha went to Candalakappa and stayed in Todeyya’s Mango grove. When Dhānañjānī told Saṅgārava that he was there, Saṅgārava visited him and questioned him on his views on brahmins. The Buddha said he had great regard for brahmins who had here and now won the goal, having discovered unaided a doctrine before unknown. He himself was one of these. He then proceeds to describe how he came to leave the household life and how, in due course, he won Enlightenment. Saṅgārava asks further whether there are any gods. The Buddha answers that of that there is no doubt; the whole world is in agreement on that point. Saṅgārava is pleased and accepts the Buddha as his teacher. MN.ii.209ff.
The Saṃyutta SN.i.182f. mentions a Saṅgārava who is perhaps distinct from the above. He lived in Sāvatthī and was a “bath ritualist,” believing in purification by water, bathing morning and evening. The Buddha, at Ānanda’s request, visited his house and preached to him the Doctrine, after which he became the Buddha’s follower.
Another Saṃyutta passage SN.v.121f. contains a sutta in which the brahmin Saṅgārava visits the Buddha and asks him why he can remember certain mantras with great case and others not at all. It may be this same brahmin who is mentioned several times also in the Aṅguttara. AN.i.168f. AN.iii.230f. AN.v.232 AN.v.252
