SB 5.9.8
pitary uparate bhratara enam atat-prabhava-vidas trayyam vidyayam eva paryavasita-matayo na para-vidyayam jada-matir iti bhratur anusasana-nirbandhan nyavrtsanta.
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
After the father died, the nine stepbrothers of Jada Bharata, who considered Jada Bharata dull and brainless, abandoned the father’s attempt to give Jada Bharata a complete education. The stepbrothers of Jada Bharata were learned in the three Vedas — the Rg Veda, Sama Veda and Yajur Veda — which very much encourage fruitive activity. The nine brothers were not at all spiritually enlightened in devotional service to the Lord. Consequently they could not understand the highly exalted position of Jada Bharata.
