तमसशक्ष् तथा सत्त्वं सत्त्वस्याव्यक्तमेव च | अव्यक्त: सत्त्वसंयुक्तो देवलोकमवाप्नुयात्,सत्त्गगुणके साथ रजोगुण, रजोगुणके साथ तमोगुण, तमोगुणके साथ सत्त्वगुण तथा सत्त्गगुणके साथ अव्यक्त (जीवात्मा)-का सम्मिश्रण देखा जाता है (यह दो तत्त्वोंका संयोग या मेल ही द्वन्द्द है)। जीवात्मा जब सत्त्वगुणसे संयुक्त होता है, तब देवलोकको प्राप्त होता है
tamasaḥ kṣaḥ tathā sattvaṃ sattvasyāvyaktam eva ca | avyaktaḥ sattva-saṃyukto devalokam avāpnuyāt ||
Yājñavalkya said: “In the interplay of the guṇas, one observes conjunctions—tamas with rajas, rajas with tamas, tamas with sattva, and even sattva with the Unmanifest (Avyakta), the subtle self-principle. This mutual joining of two factors is what is meant by ‘dvandva’ (duality). When the individual self is conjoined with sattva, it attains the world of the gods.”

The verse teaches that lived experience arises from conjunctions of principles—especially the guṇas—and that the quality of one’s association (saṃyoga) determines one’s destination: association with sattva leads upward to devaloka.
In Śānti Parva’s philosophical instruction, Yājñavalkya explains how mixtures of tamas, rajas, sattva, and the Unmanifest are perceived as ‘duality’ (dvandva), and he states the karmic-cosmological result that a sattva-associated self reaches the divine realm.
