Mbh 12.283.9a

"'"Brahman said, 'O puissant one, the deities will henceforth yield thee a share of the sacrificial offerings! O Lord of all the deities, let this wrath of thine be withdrawn by thee! O scorcher of foes, there, those gods, and the Rishis, in consequence of thy wrath, O Mahadeva, have become exceedingly agitated. This Being also, that hath sprung from thy sweat, O foremost of gods, shall wander among creatures, O righteous-souled one, under the name of Fever. O puissant one, if the energy of this Being remains all collected together, then the entire earth herself will not be able to bear him. Let him, therefore, be distributed into many parts.' When Brahman had said these words, and when his proper share was appointed of the sacrificial offerings, Mahadeva replied unto the Grandsire of great energy, saying, 'So be it.' Indeed, the wielder of Pinaka, viz., Bhava, smiled a little and became filled with joy. And he accepted the share that the Grandsire appointed of the offerings in sacrifices. Conversant with the properties of everything, Mahadeva then distributed Fever into many portions, for the peace of all creatures. Listen, O son, as to how he did this. The heat that is perceptible in the heads of elephants, the bitumen of mountains,[1402] the moss that floats on water, the slough of snakes, the sores that appear in the hoofs of bulls, the sterile tracts of earth that are full of saline matter, the dullness of vision of all animals, the diseases that appear in the throats of horses, the crests appearing on the heads of peacocks, the eye-disease of the koel,[1403] each of these was named Fever by the high-souled Mahadeva. This is what has been heard by us. The liver-disease also of sheep, and the hiccup of parrots are also each known as forms of Fever. To this must be added the toil that tigers undergo, for that also, O righteous king, is known as a form of Fever.
