Srimad-Bhagavatam: Canto 9 - Chapter 1 - Verse 2-3
Sanskrit:
योऽसौ सत्यव्रतो नाम राजर्षिर्द्रविडेश्वर: ।ज्ञानं योऽतीतकल्पान्ते लेभे पुरुषसेवया ॥ २ ॥स वै विवस्वत: पुत्रो मनुरासीदिति श्रुतम् ।त्वत्तस्तस्य सुता:प्रोक्ता इक्ष्वाकुप्रमुखा नृपा: ॥ ३ ॥
ITRANS:
yo ’sau satyavrato nāmarājarṣir draviḍeśvaraḥjñānaṁ yo ’tīta-kalpāntelebhe puruṣa-sevayā
Translation:
Satyavrata, the saintly king of Draviḍadeśa who received spiritual knowledge at the end of the last millennium by the grace of the Supreme, later became Vaivasvata Manu, the son of Vivasvān, in the next manvantara [period of Manu]. I have received this knowledge from you. I also understand that such kings as Ikṣvāku were his sons, as you have already explained.
