Why Couldn’t Arjuna Retire And Meditate On Krishna

"O Govinda, of what avail to us are kingdoms, happiness or even life itself when all those for whom we may desire them are now arrayed in this battlefield? O Madhusudana, when teachers, fathers, sons, grandfathers, maternal uncles, fathers-in-law, grandsons, brothers-in-law and all relatives are ready to give up their lives and properties and are standing before me, then why should I wish to kill them, though I may survive? O maintainer of all creatures, I am not prepared to fight with them even in exchange for the three worlds, let alone this earth." (Arjuna, Bhagavad-gita, 1.32-35)
