At the prayer of Heramba, who was petitioned by Hari, Brahmā, and the others enveloped by the fire of poison, the Supreme Śakti, who has the form of the womb that is the cause of the universe, manifested from the pleased Sadāśiva; in this connection, the sūta named Lomaśa, questioned by Śaunaka and others, describes the account of Heramba's origin; therein, the account of Heramba's birth from the Supreme Śakti; the wise Gaṇeśa praises the glorious Śiva accompanied by Śakti; pleased by Heramba's praise, [Śiva] in the form of a liṅga swallows the kālakūṭa poison; then all the gods and daityas praise the liṅga; Śiva, pleased by their praise, manifests; after consuming the hālāhala poison, Śiva instructs that the worship of Gaṇeśa must be performed at the beginning of all undertakings. 17
