PURPORT

During Lord Brahma's day, fourteen Manus or one thousand maha-yugas pass away. Brahma informed King Kakudmi that twenty-seven maha-yugas, each consisting of the four periods Satya, Treta, Dvapara 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.
