यथायथा तपोवृद्धिस्तस्याः सञ्जायते द्विजाः । तथा रूपं च कांतिश्च शरीरे प्रतिवर्धते
yathāyathā tapovṛddhistasyāḥ sañjāyate dvijāḥ | tathā rūpaṃ ca kāṃtiśca śarīre prativardhate
Hỡi các bậc nhị sinh, khi khổ hạnh của nàng càng ngày càng tăng trưởng, thì sắc đẹp và hào quang cũng theo đó mà lớn dần trên thân thể nàng.
Sūta (deduced from adhyāya context)
Type: peak
Listener: Dvijāḥ (explicitly addressed: ‘O twice-born ones’)
Scene: The maiden’s body subtly transforms: a luminous aura intensifies, skin gleams, eyes shine; the forested peak seems to brighten around her, suggesting tapas-tejas affecting the environment.
Tapas refines the person; spiritual discipline is portrayed as producing inner and outer luminosity (kānti).
This verse describes the effect of tapas within the ongoing tīrtha-narrative; it does not name a particular tīrtha by itself.
No specific rite is listed; the emphasis is on sustained tapas/vow-observance as a dharmic practice.
