Krishna describes the absolute, laser-like focus of a person bathed in the light of the Sun from Verse 16. He outlines four vectors of alignment: Their intellect is totally directed toward That Supreme (tad-buddhayaḥ). Their mind and core identity are absorbed in That (tad-ātmānaḥ). Their steady faith and discipline are anchored in That (tan-niṣṭhāḥ). Their ultimate refuge and highest goal is exclusively That (tat-parāyaṇāḥ). Because their impurities and sins are completely washed away by this knowledge (jñāna-nirdhūta-kalmaṣāḥ), they go to the state of no return (gacchanty apunar-āvṛttiṃ).
