Matsya Purana — Solar Dynasty Prelude: Vivasvān–Saṃjñā–Chāyā
अभिषिच्य मनुः पुत्रम् इलं ज्येष्ठं स धार्मिकः जगाम तपसे भूयः स महेन्द्रवनालयम् //
abhiṣicya manuḥ putram ilaṃ jyeṣṭhaṃ sa dhārmikaḥ jagāma tapase bhūyaḥ sa mahendravanālayam //
Having anointed his eldest son Ila as king, the righteous Manu departed once more for austerities, going to the forest-dwelling at Mahendra.
This verse does not directly describe Pralaya; it highlights post-succession conduct—Manu stabilizes worldly order by enthroning an heir and then turns to tapas, a Purāṇic pattern that supports cosmic and social continuity.
It presents a Rajadharma ideal: a ruler ensures orderly succession (abhiṣeka of the eldest/fit heir) before pursuing renunciation; governance and spiritual life are shown as sequential responsibilities rather than competing aims.
The ritual element is the royal abhiṣeka (consecration/anointing), a key coronation rite; no Vāstu or temple-building rule is stated, but the verse underscores the legitimacy conferred through proper ritual installation.
