Authorities say that Mārkaṇḍeya Ṛṣi, the son of Mṛkaṇḍu, was an exceptionally long-lived sage who was the only survivor at the end of Brahmā’s day, when the entire universe was merged in the flood of annihilation. But this same Mārkaṇḍeya Ṛṣi, the foremost descendant of Bhṛgu, took birth in my own family during the current day of Brahmā, and we have not yet seen any total annihilation in this day of Brahmā. Also, it is well known that Mārkaṇḍeya, while wandering helplessly in the great ocean of annihilation, saw in those fearful waters a wonderful personality — an infant boy lying alone within the fold of a banyan leaf. O Sūta, I am most bewildered and curious about this great sage, Mārkaṇḍeya Ṛṣi. O great yogī, you are universally accepted as the authority on all the Purāṇas. Therefore kindly dispel my confusion.
