Paraśurāma Avenges Jamadagni; Restoration Through Sacrifice; Viśvāmitra’s Line and Devarāta (Śunaḥśepha)
पितु: कायेन सन्धाय शिर आदाय बर्हिषि । सर्वदेवमयं देवमात्मानमयजन्मखै: ॥ २० ॥
pituḥ kāyena sandhāya śira ādāya barhiṣi sarva-devamayaṁ devam ātmānam ayajan makhaiḥ
Thereafter, Paraśurāma joined his father’s head to the dead body and placed the whole upon kuśa grass. By offering sacrifices, he began to worship Lord Vāsudeva, the all-pervading Paramātmā within all the devas and every living being.
This verse states that the Supreme Lord (the ātmā, the indwelling Self) embodies and includes all the demigods, so worship directed to Him is ultimately worship of the divine source of all devas.
In the narrative context of Canto 9, Paraśurāma honors and restores his father Jamadagni after the violent events surrounding the family, performing Vedic rites as an act of duty and reverence.
It teaches honoring elders and sacred duties while remembering that all worship and goodness culminate in devotion to the Supreme Lord, the inner Self and source of all divine powers.
