In every Kalpa Puranas are written and the author who writes the Puranas after careful analysis of the Vedas is known as Vyasa. The name of Vyasa in the current Kalpa is Dwaipayan and the name of Vyasa in the next Kalpa will be Ashwathama. Puranas in all the Kalpas are written during the Dwapara Yuga and the purpose is to spread spiritual knowledge of the Vedas in the Kali Yuga. It is impossible for men and women in Kali Yuga to follow Vedic Austerities and thus Puranas are the means to realize the knowledge of the Vedas.
