सरस्वती रजो रूपा तमोरूपा कलिंदजा । सत्त्वरूपा च गंगात्र नयंति ब्रह्मनिर्गुणम्
sarasvatī rajo rūpā tamorūpā kaliṃdajā | sattvarūpā ca gaṃgātra nayaṃti brahmanirguṇam
Here, Sarasvatī is of the nature of rajas; the Kalindajā (Yamunā) is of the nature of tamas; and Gaṅgā is of the nature of sattva—together they lead one to the attributeless Brahman.
Skanda (deduced for Kāśīkhaṇḍa discourse)
Tirtha: Triveṇī-saṅgama (Prayāga)
Type: sangam
Scene: Three river-goddesses meet: Sarasvatī tinted with dynamic red (rajas), Yamunā with deep indigo/black (tamas), Gaṅgā with luminous white/gold (sattva); above them shines a formless, radiant expanse signifying nirguṇa Brahman.
The confluence is presented as a spiritual synthesis: transcending the guṇas through the sacred rivers leads toward nirguṇa realization.
Prayāga’s Triveṇī Saṅgama (Gaṅgā–Yamunā–Sarasvatī).
Implicitly, saṅgama-snāna (bathing at the confluence) as a means toward purification and liberation.
