yavad dinam bhagavato
manun bhuñjams catur-dasa
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
After the end of Brahma’s night, the creation of the three worlds begins again in the daytime of Brahma, and they continue to exist through the life durations of fourteen consecutive Manus, or fathers of mankind.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
At the end of the life of each Manu there are shorter dissolutions also.
