Roar

Then Susharma, piercing Partha with ten shafts, struck Janardana with three in the right arm. With a broad-headed arrow then, O sire, he pierced the standard of Arjuna. Thereupon that foremost of apes, of huge dimensions, the handiwork of the celestial
artificer himself, began to utter loud sounds and roared very fiercely, affrighting thy troops. Hearing the
roars of the ape, thy army became inspired with fear. Indeed, under the influence of a great fear, that
army became perfectly inactive. That army then, as it stood inactive, O king, looked beautiful like the
Citraratha forest with its flowery burthen of diverse kinds. Then those warriors, recovering their senses,
O chief of the Kurus, began to drench Arjuna with their arrowy downpours like the clouds drenching the
mountains.
