-- Meghadūtaṃ, 1.2.

[Separated from his wife, having passed several months on these hills pining with desire, his arm having become bare by the slipping off of the golden bracelet;] on the first day of Āṣāḍha he saw a mountain-top-embracing cloud, to all appearance, like a butting elephant preparing to thrust against a wall.

-- (Tr. Courtesy: Colonel H. A. Ouvry, The Meghadūta or Cloud Messenger by Kālidāsa, Williams & Norgate, Edingburgh,1868)
