Brihat Samhita
असितघननिरुद्धं एव वा चलिततडित्सुरचापचित्रितम् । द्विपमहिषकुलऽकुलीकृतं वनं इव दावपरीतं अम्बरम् ॥ २४-१५ ॥
The dense, dark clouds may be compact and still, or marked by moving lightning streaks like the bow of a deity; the sky appears like a forest shaken by herds of buffaloes, as if the heavens themselves were overturned.
