Rāmāyaṇacampū 1.48

1.48

Then, having entered Siddhāśrama, Viśvāmitra commenced the sacrifice.
Immediately after, seeing that flock of demons descend from mid-air, terrifying as the army of Death, the disciples of the son of Kuśika, fleeing with the sacrificial sticks and kuśa grass falling from their hands, reported in agitation to the descendant of Raghu, who was eager for battle:
"Seizing mountain peaks and hurling them all around, laughing, in fury / clapping their hands, standing here and there, dancing again and again, / sprinkling the earth with blood, binding sky-dwellers with a garland made of entrails, / scorching with eyes like fire, the night-roamers block the opening of the heavens."
