नारद-समङ्ग-संवादः — The Nārada–Samaṅga Dialogue on Fearlessness and Equanimity
सुसुखं बत जीवामि यस्य मे नास्ति किंचन । मिथिलायां प्रदीप्तायां न मे दह्युति किंचन
su-sukhaṃ bata jīvāmi yasya me nāsti kiṃcana | mithilāyāṃ pradīptāyāṃ na me dahyati kiṃcana ||
毗湿摩说道：“诚然，我安乐而生，因为无有一物属于我。纵使弥提罗城尽成火海，我亦无物可焚。”（此语相传出自阇那迦王，旨在阐明无执无取：若离“我所有”（mamatā）之心，纵逢损失、灾厄与动荡，内在亦不为所摇。）

Educational Q&A
The verse teaches aparigraha/non-possessiveness: when one abandons the sense of ownership (‘mine-ness’), one remains inwardly secure even if external possessions, status, or the whole city/kingdom is destroyed.
In the Shanti Parva’s instruction on dharma and right conduct, Bhishma cites (or echoes) King Janaka’s famous declaration to illustrate the ideal of a wise ruler who is inwardly detached—so that even a calamity like Mithilā burning does not disturb him through personal loss.
