Mahabharata Anushasna Parva Chapter 139:2

Mahabharata Anushasna Parva (Dana Dharma Parva) Chapter 139:2 Soon the summit of that mountain presented a distressing and pitiful appearance, Inhabited by animals of diverse kinds which began to utter cries of woe and pain, the summit soon became bereft of every living creature. That fire of mighty flames, having consumed everything without leaving a remnant at last came back to Vishnu and touched his feet like a docile disciple. That crusher of foes, viz., Krishna, beholding that mountain burnt, cast a benignant look upon it and thereby brought it back to its former condition. That mountain thereupon once more became adorned with flowering trees and creepers, and once more echoed with the notes and cries of birds and deer and animals of prey and reptiles. Seeing that wonderful and inconceivable sight, all the ascetics became amazed. Their hairs stood on end and their vision was blurred with tears. That foremost of speakers, Narayana, beholding those Rishis thus filled with wonder, addressed them in these sweet and refreshing words, 'Why, indeed, has wonder filled the hearts of this assemblage of Rishis, these ascetics that are always free from attachment of every kind, that are divested of the idea of meum, and that are fully conversant with every sacred science? It behoveth these Rishis possessed of wealth of penances and freed from every stain to explain to me truly this doubt that has arisen in my mind.' The Rishis said, 'It is thou that createst all the worlds, and it is thou that destroyest them again. It is thou that art Winter, it is thou that art Summer, and it is thou that art the season of rains. Of all the creatures, mobile and immobile, that are found on the earth, thou art the father, thou art the mother, thou art the master, and thou art the origin! Even this, O slayer of Madhu, is a matter of wonder and doubt with us. O source of all auspiciousness, it behoveth Thee to resolve to us that doubt, viz., the issue of fire from Thy mouth. Our fears being dispelled we shall then, O Hari, recite to thee what we have heard and seen.' Vasudeva said, 'The fire that issued from my mouth and that resembles the all-consuming Yuga-fire in splendour, and by which this mountain has been crushed and scorched, is nothing else than the energy of Vishnu. Ye Rishis, ye are persons that have subjugated wrath, that have brought your senses under complete control, that are endued with wealth of penances, and that are very gods in puissance. Yet ye have suffered yourselves to be agitated and distressed! I am now engaged wholly with the observances relating to rigid vow. Verily, in consequence of my observing the vows of an ascetic, a fire issued from my mouth. It behoves you not to suffer yourselves to be agitated. It is for observing a rigid vow that I came to this delightful and auspicious mountain. The object that has brought me here is to acquire by the aid of penances a son that would be my equal in energy. In consequence of my penances, the Soul existing in my body became transformed into fire and issued out of my mouth. That fire had repaired to behold the boon-giving Grandsire of all the universe. The Grandsire, ye foremost of ascetics, told my soul that half the energy of the great god having the bull for his device would take birth as my son. That fire returning from its mission, has come back to me and approached my feet like a disciple desirous of serving me dutifully. Indeed, casting off its fury it has come back to me to its own proper nature. I have thus told you, in brief, a mystery appertaining to Him who has the lotus for his origin and who is endued with great intelligence.
