चतुर्युगाख्यान (Caturyuga-Ākhyāna) — Yuga-wise Origins and Measurements of Beings
प्रवर्त्तते तथा द्वौ तु यथा मत्स्योदके उभे / चेतनाधिष्ठितं सत्त्वं प्रवर्त्तति गुणात्मकम्
pravarttate tathā dvau tu yathā matsyodake ubhe / cetanādhiṣṭhitaṃ sattvaṃ pravarttati guṇātmakam
The two proceed together, like fish and water within the waters; sattva, upheld by Consciousness, functions as a nature constituted of the guṇas.
