The Bhojas are one of the Yadu clans, named with the Vrishnis and Andhakas. At SB 3.3.24 the young Yadus and Bhojas at play in the city offended the sages skilled in the Lord's teaching, and at SB 3.3.25 the Vrishnis, Bhojas, Andhakas and the rest went to Prabhasa, deluded by the gods. This is the beginning of the end of the Yadu line.
