Mbh 13.140.2c

The great Rishis, beholding Mahadeva, bowed to him by touching the ground with their heads. Endued with forgiving souls, they all became (in consequence of the sight they had obtained of the great deity) freed from every sin and thoroughly cleansed. The retreat of that lord of all creatures with many terrible forms, shone with a peculiar beauty. Abounding with many large snakes, it became unapproachable and unbearable (by ordinary beings). Within the twinkling of the eye, O slayer of Madhu, everything there became exceedingly wonderful. Indeed, the abode of that great deity having the bovine bull for his device began to blaze with a terrible beauty. Unto Mahadeva seated there, came his spouse, the daughter of Himavat, surrounded by the wives of the ghostly beings who are the companions of the great deity. Her attire was like that of her lord and the vows she observed were like those of his. She held a jar on her loins that was filled with the waters of every Tirtha, and was accompanied by the presiding deities (of her own sex) of all the mountain streams. Those auspicious ladies walked in her train. The goddess approached raining flowers on every side and diverse kinds of sweet perfumes. She who loved to reside on the breast of Himavat advanced in this guise towards her great lord. The beautiful Uma, with smiling lips and desirous of playing a jest, covered from behind, with her two beautiful hands, the eyes of Mahadeva. As soon as Mahadeva's eyes were thus covered, all the regions became dark and life seemed to be extinct everywhere in the universe. The Homa rites ceased. The universe became suddenly deprived of the sacred Vashat also. All living creatures became cheerless and filled with fear. Indeed, when the eyes of the lord of all creatures were thus closed, the universe seemed to become sunless. Soon, however, that overspreading darkness disappeared. A mighty and blazing flame of fire emanated from Mahadeva's forehead.
