Mbh 7.202.4b

Even unto those that are afflicted by all the evil planets, even unto those that are stained with every sin, that great protector, if they seek him, becomes gratified with them and granteth them salvation. He granteth, and taketh away life and health and prosperity and wealth and diverse kinds of objects of desire. The prosperity is his that is seen in Indra and other gods. He is ever engaged in the good and evil of men in this world. In consequence of his supremacy, he can always obtain whatever objects he desires. He is called Maheswara and is the lord of even the supreme ones. In many forms of many kinds he pervadeth the universe. The mouth which that God has is in the ocean. It is well-known that mouth, assuming the form of a mare’s head, drinketh the sacrificial libation in the shape of water. This god always dwelleth in crematoriums. Men worship that Supreme lord in that place where none but the courageous can go. Many are the blazing and terrible forms of this God that men speak of and worship in the world. Many also are the names, of truthful import, of this Deity in all the worlds. Those names are founded upon his supremacy, his omnipotence, and his acts. In the Vedas the excellent hymn called Sata Rudriya, hath been sung in honour of that great God called the infinite Rudra. That God is the lord of all wishes that are human and heavenly. He is omnipotent, and he is the supreme master. Indeed, that God pervadeth the vast universe. The Brahmanas and the Munis describe him as the First-born of all creatures. He is the First of all the gods; from his mouth was born Vayu (the wind). And since he always protecteth the creatures (of the universe) and sporteth with them, and since also he is the lord of all creatures, therefore is he called Pasupati. And since his Phallic emblem is always supposed to be in the observance of the vow of Brahmacharya, and since he always gladden the world, therefore he is called Maheswara.
