Mbh 13.141.1

"'"'The blessed and holy one said, "In days of yore, a blessed woman was created by Brahman, called Tilottama, by culling grains of beauty from every beautiful object in the universe. One day, that lady of beautiful face, unrivalled in the universe for beauty of form, came to me, O goddess, for circumambulating me but really impelled by the desire of tempting me. In whatever direction that lady of beautiful teeth turned, a new face of mine instantly appeared (so eager did I become to see her). All those faces of mine became agreeable to look at. Thus, in consequence of the desire of beholding her, I became four-faced, through Yoga-puissance. Thus, I showed my high Yoga-power in becoming four-faced. With that face of mine which is turned towards the east, I exercise the sovereignty of the universe. With that face of mine which is turned towards the north, I sport with thee, O thou of faultless features! That face of mine which is turned towards the west is agreeable and auspicious. With it I ordain the happiness of all creatures. That face of mine which is turned towards the south is terrible. With it I destroy all creatures. I live as a Brahmacharin with matted locks on my head, impelled by the desire of doing good to all creatures. The bow Pinaka is always in my hand for accomplishing the purposes of the deities. In days of yore, Indra, desirous of acquiring my prosperity, had hurled his thunderbolt at me. With that weapon my throat was scorched. For this reason I have become blue-throated."
