20. Now, in the context of the māhātmya of Śivatīrtha, the description of the account of Śrī Śaṃkara's rebirth; therein, the description of the seed-syllables of the Kūṭamantra by Śiva to Pārvatī; the Goddess's attainment of a corrupted mind through the recitation of such a mantra; now, Śiva's going to Dharmāraṇya and falling down suddenly; from the sweat of his limbs, the emergence of the Kūṭagaṇas; when those gaṇas, standing upon the Kālakūṭa poison, practiced the Kūṭamantra and achieved perfection, Pārvatī's feeling ashamed upon hearing them address Śiva as identical to themselves; then, by Śiva's command, Pārvatī pleasing Śiva by performing austerities; the renown of that place of austerities under the name of Dharākṣetra; and the description of the māhātmya of that Dharākṣetra. 13
