manavo ’smin vyatitah sat
adyas te kathito yatra
devadinam ca sambhavah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sukadeva Gosvami said: In the present kalpa there have already been six Manus. I have described to you Svayambhuva Manu and the appearance of many demigods. In this kalpa of Brahma, Svayambhuva is the first Manu.
