गङ्गातरणम्, सुमन्त्र-प्रतिनिवर्तनम्, जटाधारणम् (Crossing the Gaṅgā; Sumantra’s Return; Adoption of Ascetic Signs)
अहं किं चापि वक्ष्यामि देवीं तव सुतो मया।नीतोऽसौ मातुलकुलं सन्तापं मा कृथा इति।।2.52.45।।
ahaṃ kiṃ cāpi vakṣyāmi devīṃ tava suto mayā | nīto ’sau mātula-kulaṃ santāpaṃ mā kṛthā iti ||
What could I possibly say to Queen Kauśalyā—“Your son has been taken by me to his maternal uncle’s house; do not grieve”—as though that were the truth?
What shall I say to Kausalya? Shall I say 'O venerable queen! I have left your son at his maternal uncle's, hence don't grieve'.
Satya (truthfulness) is central: Sumantra refuses to mask a painful reality with a convenient falsehood, even if the lie might momentarily reduce grief.
Sumantra worries about how he can face Kauśalyā in Ayodhyā and report that Rāma is gone to the forest.
Integrity in speech (satya) joined with compassion—he fears causing pain, yet will not deceive.
