रामः Rama, रणे in war, दुरावारान् those difficult to stop, दुर्विषहान् unbearable ones, कालदण्डोपमान् those looking like Yama's staff, अजिह्मगान् going straight without missing the goal, कङ्कपत्रान् arrows furnished with herons' feathers, लीलया very easily, मुमोच discharged.
As if sporting, Rama discharged the arrows attached with herons' feathers. The arrows were inescapable, unbearable like that of Yama's staff, that went straight without missing the target.
