चतुर्युगाख्यान (Caturyuga-Ākhyāna) — Yuga-wise Origins and Measurements of Beings
ऋचो यजूंषि समानि यथा च प्रतिदैवतम् / आभूतसंप्लवस्यापि वर्ज्यैकं शतरुद्रियम्
ṛco yajūṃṣi samāni yathā ca pratidaivatam / ābhūtasaṃplavasyāpi varjyaikaṃ śatarudriyam
The Ṛk, the Yajus, and the Sāman hymns—together with the recitations for each deity—endure until the bhūta-saṃplava (cosmic dissolution), save for one alone: the Śatarudrīya.
