Srimad Bhagavatam Canto 09, Chapter 06, Text 10

SB 9.6.10

sa tu viprena samvadam
 jñapakena samacaran
tyaktva kalevaram yogi
 sa tenavapa yat param
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Having been instructed by the great and learned brahmana Vasistha, who discoursed about the Absolute Truth, Maharaja Iksvaku became renounced. By following the principles for a yogi, he certainly achieved the supreme perfection after giving up his material body.
