Understanding matters thus in full light, seekers in the past had performed their activities well. Therefore, you too do yours, as did your predecessors.
Here Krishna comes to human-level and aligns himself with many others of the past. Seekers of yore, he says, had plunged into their activities, without resistance or remorse.
Krishna has already cited Janaka and the rest, who sat on the throne and pursued the most onerous task of ruling their kingdom, ensuring the welfare of people, a mission full of challenges, strifes and hazards. Of the many vital tasks the society needs, ruling is the most crucial.
Why should Arjuna then feel doubtful about battling, a duty all kshatriyas are given to by birth, tendencies and training? There is nothing to be reluctant or remorseful about the mission.
“You have come here to fight against fighters. Is not your grandfather clearly exhorting you and others to fight? If they have no resistance in battling, why should you have? Their presence must mean the necessary sanction and inspiration.”
