Mbh 15.30.1a

"'Kunti said, "O holy one, thou art my father-in-law and therefore, my deity of deities. Verily, thou art my god of gods. Hear my words of truth. An ascetic named Durvasas, who is of the regenerate order and who is full of wrath, came to my father's house for eleemosynary charity. I succeeded in gratifying him by the purity of my external behaviour and of my mind, as also by refusing to notice the many wrongs he did. I did not give way to wrath although there was much in his behaviour quite capable of exciting that passion. Served with care, the great ascetic became highly pleased with me and disposed to grant me a boon. 'Thou must accept the boon I shall give,' were his words to me. Fearing his curse, I answered him, saying,--'So be it.' The regenerate Rishi once more said unto me,--'O blessed damsel, O thou of beautiful face, thou wilt become the mother of Dharma. Those deities whom thou wilt summon will be obedient to thee.' Having said those words, the regenerate one vanished away from my sight. I became filled with wonder. The mantra, however, which the Rishi gave has dwelt in my memory at all times. One day, sitting within my chamber I beheld the sun rising. Desiring to bring the maker of day before me, I recollected the words of the Rishi. Without any consciousness of the fault I committed, I summoned the deity from mere girlishness. The deity, however, of a thousand rays, (summoned by me) came to my presence. He divided himself in twain. With one portion he was in the firmament, and with the other he stood on the Earth before me. With one he heated the worlds and with another he came to me. He told me, while I was trembling at his sight, these words,--'Do thou ask a boon of me.' Bowing unto him with my head, I asked him to leave me. He replied unto me, saying,--'I cannot bear the idea of coming to thee fruitlessly. I shall consume thee as also that Brahmana who gave thee the Mantra as a boon.
