Arjuna is famous as the most expert bowman. Why, then, could he not hit the fish target at Srimati Lakshmana's svayam-vara ceremony just as he had done once before to win Draupadi? Srila Sridhara Svami explains: The target at Draupadi's svayam-vara had been covered only partially, so that a marksman could see it if he looked straight up the pillar on which it was placed. To shoot Lakshmana's target, however, it was necessary to aim by looking up and down at the same time, an impossible feat for any mortal. Therefore only Krishna could strike the target.
