A yakkha chieftain whose help should be sought by followers of the Buddha, when in distress (D.iii.205). The Buddha says (M.i.201 f ) that Digha once visited him and spoke to him of the wonderful attainments of Anuruddha, Nandiya, and Kimbila, and remarked how fortunate were the Vajjī that these three were dwelling in the Vajji country. Buddhaghosa (MA.i.431) describes Digha as a devarājā and says that his other name was Parajana. His visit to the Buddha was at Gosiṅgasālavanadāya, just before the Buddha left to see Anuruddha and the others.
