tatas cänudinam dharmah
satyam saucam ksamä dayä
kälena balinä räjan
nanksyaty äyur balam smritih
“My dear King, with each day religion, truthfulness, cleanliness, forgiveness, mercy, duration of life, bodily strength, and memory will all decrease more and more by the mighty force of time.” [Srimad-Bhägavatam 12.2.1]
This description of the Kali-yuga [the present age of quarrel and hypocrisy] is given in the Twelfth Canto of Srimad-Bhägavatam. Srimad-Bhägavatam was written five thousand years ago, when the Kali-yuga was about to begin, and many things that would happen in the future are spoken of there. Therefore we accept Srimad-Bhägavatam as sastra [revealed scripture]. The compiler of sästra (the sästra-kära) must be a liberated person so that he can describe past, present, and future.
