Genealogies of Svāyambhuva Manu, the Appearance of Yajña, and Atri’s Sons
Brahmā–Viṣṇu–Śiva Expansions
तेभ्योऽग्नय: समभवन्चत्वारिंशच्च पञ्च च । त एवैकोनपञ्चाशत्साकं पितृपितामहै: ॥ ६१ ॥
tebhyo ’gnayaḥ samabhavan catvāriṁśac ca pañca ca ta evaikonapañcāśat sākaṁ pitṛ-pitāmahaiḥ
From those three sons arose another forty-five descendants, also fire-gods. Thus the fire-gods number forty-nine in all, including the fathers and the grandfather.
The grandfather is Agni, and the sons are Pāvaka, Pavamāna and Śuci. Counting these four, plus forty-five grandsons, there are altogether forty-nine different fire-gods.
This verse states that forty-five fires were born, and counting along with their fathers and grandfathers the total becomes forty-nine.
Śukadeva Gosvāmī is narrating to King Parīkṣit as part of the genealogical account in Canto 4, Chapter 1.
It reminds a student of the Bhagavatam that the universe is ordered and purposeful, encouraging reverence for sacred forces like fire (used in yajña and worship) and gratitude toward forefathers and tradition.
