Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
You have also described [at the end of the Fifth Canto] the varieties of hellish life that result from impious activities, and you have described [in the Fourth Canto] the first manvantara, which was presided over by Svayambhuva Manu, the son of Lord Brahma.
