TRANSLATION
Twenty-seven  catur-yugas  have already passed. Those upon whom you may have decided are now gone, and so are their sons, grandsons and other descendants. You cannot even hear about their names.
PURPORT
During Lord Brahmā's day, fourteen Manus or one thousand  mahā-yugas  pass away. Brahmā informed King Kakudmī that twenty-seven  mahā-yugas , each consisting of the four periods Satya, Tretā, Dvāpara and Kali, had already passed. All the kings and other great personalities born in those  yugas  had now departed from memory into obscurity. This is the way of time as it moves through past, present and future.
