a mahayuga consists of satya or krita yuga, treta yuga, dvapara yuga and kali yuga. A cycle of creation is known as a manvantara, presided over by a Manu. Vaivasvata Manu is the Manu who presides over our current manvantara. Every manvantara has just over seventy-one mahayugas and in our current manvantara, we are now in the twenty-eighth mahayuga.
