A brahmin who visited the Buddha at Jetavana and stated that a man can be purified only by knowledge of the Vedas. The Buddha answered that it is not knowledge of runes, but the purity of heart of a man, which is important, of a man who has put forth effort to win supreme purity of conduct (S.i.165).
Buddhaghosa says (SA.i.179) that the brahmin was called Suddhika to distinguish him from other Bháradvájas by the nature of his enquiry.
