vasistha-tanayah sapta
rsayah pramadadayah
satya vedasruta bhadra
deva indras tu satyajit
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
During the reign of the third Manu, Pramada and other sons of Vasistha became the seven sages. The Satyas, Vedasrutas and Bhadras became demigods, and Satyajit was selected to be Indra, the King of heaven.
