Matsya Purana — Kārtavīrya Arjuna’s Solar Boon and the Genealogy from Kroṣṭu to the Yādava Lines
तेभ्यः प्रव्राजितो राज्याज् ज्यामघस्तु तदाश्रमे प्रशान्तश्चाश्रमस्थश्च ब्राह्मणेनावबोधितः //
tebhyaḥ pravrājito rājyāj jyāmaghastu tadāśrame praśāntaścāśramasthaśca brāhmaṇenāvabodhitaḥ //
Driven out by them from his kingdom, Jyāmagha went to that hermitage; there, becoming calm and living as an āśrama-dweller, he was instructed by a brāhmaṇa and awakened to right understanding.
This verse does not address Pralaya; it focuses on a historical-ethical episode where a king, exiled from his realm, is reformed through āśrama life and brāhmaṇa instruction.
It frames a key Rajadharma theme: when royal power is lost, a king should not collapse into anger or despair but turn to restraint, disciplined living, and guidance from learned brāhmaṇas—restoring inner order before reclaiming outer authority.
No Vāstu or temple-building rule is stated; the only ritual-cultural marker is the āśrama setting, highlighting the hermitage as a space of instruction, tapas, and ethical recalibration.
