Pitāmaha-sabhā-varṇana & Hariścandra-māhātmya
Description of Brahmā’s Assembly and the Eminence of Hariścandra
संवत्सरा: पञ्च युगमहोरात्रश्नतुर्विध: । कालचक्र च तद् दिव्यं नित्यमक्षयमव्ययम्
saṃvatsarāḥ pañca yugam ahorātraś caturvidhaḥ | kālacakraṃ ca tad divyaṃ nityam akṣayam avyayam ||
Nārada said: “Five years make up a yuga; and the day-and-night cycle is spoken of as fourfold. This divine Wheel of Time turns everlastingly—constant, inexhaustible, and undecaying.”
