सुमन्त्रदर्शनम् तथा रामस्य राजदर्शनाय प्रस्थानम् (Sumantra Meets Rama; Rama Departs to See the King)
तया सुचरितं देव्या पुरा नूनं महत्तपः।।।।रोहिणीव शशाङ्केन रामसंयोगमाप या।
tayā sucaritaṃ devyā purā nūnaṃ mahattapaḥ |
rohiṇīva śaśāṅkena rāmasaṃyogam āpa yā ||
Surely, in former times that noble lady performed great austerities; therefore she attained union with Rama—like Rohiṇī with the Moon.
Sita was united with Rama like Rohini with the Moon surely because of her great austerities performed in the past. (They observed).
The verse reflects the karmic-ethical idea that virtue and self-discipline (tapas) bear fitting results—here, the ‘deserved’ companionship of a righteous spouse.
Ayodhya’s women interpret Sītā’s good fortune—her union with Rama—as the fruit of past austerities, using a celestial simile.
Sītā’s spiritual merit and disciplined virtue (tapas), understood as the foundation of her auspicious destiny.
