言大梵壽量六十中劫者，舊來相傳皆云：梵王但經五十八中劫。少二中劫，所以者何？於成劫中，初一別劫，成器世間，梵王未來，但經十九劫後，壞劫時一劫火起，梵王亦無，是則梵王，於一大劫八十劫內除正空時，有二十劫，於成壞時，各除一劫，但壽五十八劫，而言壽命六十中劫，合為一劫者，從多總判，故智度論云：梵王壽命五十八劫。

Regarding the lifespan of Mahābrahmā being sixty intermediate kalpas: traditionally, it has always been transmitted as: the Brahmā King undergoes only fifty-eight intermediate kalpas, lacking two intermediate kalpas. Why is this? In the kalpa of formation, during the first distinct kalpa when the receptacle world forms, the Brahmā King has not yet arrived, undergoing only nineteen kalpas; later, at the time of the kalpa of destruction, when the fire arises for one kalpa, the Brahmā King is also absent. Thus the Brahmā King, within the eighty kalpas of one great kalpa—excluding the time of actual emptiness which has twenty kalpas, and excluding one kalpa each from the times of formation and destruction—has a lifespan of only fifty-eight kalpas; and saying his lifespan is sixty intermediate kalpas combined into one kalpa is a general determination based on the majority. Therefore, the *Mahāprajñāpāramitopadeśa* states that the Brahmā King's lifespan is fifty-eight kalpas.
