The Ikṣvāku dynasty (vaṃśa) - Verse 110

Uttaṅka said:: Viśvāmitra who returned (from his penance) became delighted with Triśaṅku because he had sustained his wife (during the absence of the sage). He granted him a boon. When he was pressed to choose a boon the prince chose him as his preceptor and requested for this boon—“I shall go to heaven along with this physical body.” When there was a danger of draught extending to twelve years, the sage crowned him in his hereditary kingdom. Even as the Devas as well as Vasiṣṭha were watching, the lordly saint Viśvāmitra made him ascend heaven.
