Tāmasa Sarga, the Androgynous Division of Brahmā, and the Lineages of Dharma and Adharma
तमस्तद् व्यनुदत् पश्चात् रजः सत्त्वेन संयुतः / तत् तमः प्रतिनुन्नं वै मिथुनं समजायत
tamastad vyanudat paścāt rajaḥ sattvena saṃyutaḥ / tat tamaḥ pratinunnaṃ vai mithunaṃ samajāyata
ఆపై సత్త్వముతో సంయుక్తమైన రజస్సు ఆ తమస్సును తొలగించింది। ఆ తమస్సు ప్రతినుద్దమైయినప్పుడు నిజముగా ఒక మిథునము (యుగలము) జన్మించింది।
Purāṇic narrator (Sūta/Vyāsa tradition) describing cosmogenesis
Primary Rasa: adbhuta
Secondary Rasa: vira
By presenting creation as a play of guṇas (tamas, rajas, sattva), the verse implies the Atman/Iśvara is the witnessing principle beyond guṇa-interaction, while manifest existence arises when guṇas counteract and transform one another.
The verse supports the Yoga-shāstra emphasis on guṇa-viveka (discriminating the guṇas): cultivating sattva to subdue tamas and steady rajas—an inner discipline that later culminates in transcending all three guṇas in Pāśupata-oriented devotion and contemplation.
Though not naming them directly, the cosmological frame aligns with the Purāṇa’s non-sectarian synthesis: the same Supreme Lord (under Shiva-Vishnu unity) governs guṇa-dynamics, from which duality (mithuna) and the world-process unfold.
