tad-vamsya rsayah surah
bhavanti caiva yugapat
suresas canu ye ca tan
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
After the dissolution of each and every Manu, the next Manu comes in order, along with his descendants, who rule over the different planets; but the seven famous sages, and demigods like Indra and their followers, such as the Gandharvas, all appear simultaneously with Manu.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
There are fourteen Manus in one day of Brahma, and each of them has different descendants.
