Matsya Purana — Genealogy from Budha to Purūravas and Yayāti; Raji’s war episode; the Paurava...
अहं जरां तवादाय राज्ये स्थास्यामि चाज्ञया एवमुक्तः स राजर्षिस् तपोवीर्यसमाश्रयात् //
ahaṃ jarāṃ tavādāya rājye sthāsyāmi cājñayā evamuktaḥ sa rājarṣis tapovīryasamāśrayāt //
“I will take upon myself your old age, and, by your command, I shall remain in the kingship.” Thus addressed, that royal sage—supported by the potency born of austerity—made it so.
This verse is not about Pralaya; it highlights a moral-psychological and karmic theme—old age can be depicted as transferable in narrative, enabled by tapas (austerity-born power) within royal lineage episodes.
It emphasizes obedience to rightful authority and the weight of royal command, while also presenting tapas-vīrya as a legitimizing force in governance—suggesting that self-discipline and ethical power underpin stable kingship.
No Vāstu/temple-building or ritual procedure is stated in this verse; its significance is ethical and narrative—tapas as a power that can effect extraordinary outcomes in royal life.
