Mbh 13.161.1b

For this he is called Vahurupa (of multiform aspect). The deities called Viswedevas reside in his body. He is, for this, called Viswarupa (of universal form). He is thousand-eyed; or, he is myriad-eyed; or, he has eyes on all sides and on every part of his body. His energy issues through his eyes. There is no end of his eyes. Since he always nourishes all creatures and sports also with them, and since he is their lord or master, therefore he is called Pasupati (the lord of all creatures). Since his emblem is always observant of the vow of Brahmacharya, all the worlds worship it accordingly. This act of worship is said to gratify him highly. If there is one who worship him by creating his image, another who worships his emblem, the latter it is that attains to great prosperity for ever. The Rishis, the deities, the Gandharvas, and the Apsaras, worship that emblem of his which is ever erect and upraised. If his emblem is worshipped, Maheswara becomes highly gratified with the worshipper. Affectionate towards his devotees, he bestows happiness upon them with a cheerful soul. This great god loves to reside in crematoria and there he burns and consumes all corpses. Those persons that perform sacrifices on such grounds attain at the end to those regions which have been set apart for heroes. Employed in his legitimate function, he it is that is regarded as the Death that resides in the bodies of all creatures. He is, again, those breaths called Prana and Apana in the bodies of all embodied beings. He has many blazing and terrible forms. All those forms are worshipped in the world and are known to Brahmanas possessed of knowledge. Amongst the gods he has many names all of which are fraught with grave import. Verily, the meanings of those names are derived from either his greatness or vastness, or his feats, or his conduct. The Brahmanas always recite the excellent Sata-rudriya in his honour, that occurs in the Vedas as also that which has been composed by Vyasa.
