Abandoning all sorts of enjoyments, with control over his senses and without any food, the Daitya did Japam of the (repeated) one syllabled Mâyâ-Vija-mantra and, meditating the form of the Utmost Sakti of Mine, adorned with all ornaments, practised very terrible austerities for one thousand years. I, too, went to the place of austerities in My Tâmasî form, meditated by the Daitya and appeared before him. There, seated on the lion's back, feeling compassion for his tapasya I spoke to him:-- “O glorious One! O one of good vows! I have come to grant boon to Thee!” Hearing the words of the Devî, the Daitya instantly got up and falling down with devotion at Her feet, circumambulated Her. Looking at My form, his large eyes became cheerful with feelings of love and filled with tears; shedding tears, then, he began to chant hymns to Me.
