An eminent lay disciple of Avanti.
Once when Mahā Kaccāna was staying in the Kuraragharapapāta, Hāliddakāni visited him and consulted him at length on the subjects treated in Māgandiyapañha (S.iii.9f ) and again on those of the Sakkapañha (S.iii.13f).
On another occasion (S.iv.115f) he questioned the Elder regarding the diversity of sensations.
