Shloka 6.121.6
अग्निपरीक्षासाक्ष्यं (Agni’s Testimony and Sītā’s Revalidation)
नैववाचा न मनसानैवबुद्ध्या न चक्षुषा ।सुवृत्तावृत्तशौण्डीरन त्वामत्यचरच्छुभा ।।।।
viśuddhā triṣu lokeṣu maithilī janakātmajā |
na vihātuṁ mayā śakyā kīrtir ātmavatā yathā ||
Maithilī, Janaka’s daughter, is pure in all the three worlds. I cannot abandon her—just as a self-possessed man cannot abandon his own fame.
"Sita is of good conduct and auspicious. To you who are endowed with valour, she is faithful by speech, by intention of thought and intellect and even by glance."
Dharma is the protection of truth and rightful relationship: once Sītā’s purity is established, abandoning her would violate justice, marital duty, and moral consistency.
After Agni’s testimony, Rāma states publicly that Sītā is universally pure and therefore cannot be renounced.
Rāma’s commitment to satya and to restoring rightful honor; Sītā’s purity is affirmed as beyond dispute.
