Markandeya said: “He by whom, in the varied duties performed here, the foremost portion of food is continually offered for the sake of all beings—so that beings are sustained—he is celebrated as ‘Agraṇī’ (the Leader).” In this context, Agraṇī is identified as the fire-deity associated with the offering of the first share, and is also remembered in the genealogical tradition as a son of Manu.
मार्कण्डेय उवाच
The verse praises the dharmic principle of offering the first share (agra) before personal consumption—an ethic of prioritizing the welfare of all beings through ritualized generosity and acknowledgment of sustaining powers (Agni/offerings).
Mārkaṇḍeya is explaining the significance of the name/epithet ‘Agraṇī’: the one who leads by ensuring that, amid diverse worldly and ritual actions, the foremost portion is offered for the benefit and sustenance of beings—hence the association with Agni and traditional genealogical identification.
