Stories about Mohini and Shiva have been popular in South Indian texts.[25] In the southern version of the Bhagavata Purana, after Vishnu deceives the demons by his maya female form, Shiva sees Mohini.[26] He becomes "bereft of shame and robbed by her of good sense," runs crazily behind enchanting form, while his wife Parvati (Uma) looks on. Shiva is overcome by Kma (love and desire) in this version of mythology. Shiva's seed falls on the ground creating ores of silver and gold. Vishnu then states that emotions are difficult to overcome, and states that Maya will become a half of Shiva's Ardhanarisvara aspect. Shiva then extols Vishnu's power.[13][27]
The Tripurarahasya, a south Indian Shaktatext, retells the story, giving more importance to the Goddess. When Shiva wishes to see Vishnu's Mohini form again, Vishnu fears that he may be burned to ashes like Kamadeva by the ascetic Shiva. So, Vishnu prays to goddess Tripura, who grants half of her beauty to Vishnu, begetting the Mohini-form. As Shiva touches Mohini, his seed spills, indicating a loss of the merit gained through of all his austerities.[28]
In the Brahmanda Purana when the wandering sage Narada tells Shiva about Vishnu's Mohini form that deluded the demons, Shiva dismisses him. Shiva and his wife Parvati go to Vishnu's home. Shiva asks him to take on the Mohini form again so he can see the actual transformation for himself. Vishnu smiles, again meditates on the Goddess, and in place of Vishnu stands the gorgeous Mohini. Overcome by lust, Shiva chases Mohini as Parvati hangs her head in shame and envy. Shiva grabs Mohini's hand and embraces her, but Mohini frees herself and runs further. Finally, Shiva grabs her and their "violent coupling" leads to discharge of Shiva's seed which falls on the ground and the god Maha-Shasta ("The Great Chastiser") is born. Mohini disappears, while Shiva returns home with Parvati.[29][30]
Shasta is identified primarily with two regional deities: Ayyappa from Kerala and the Tamil Aiyanar. He is also identified with the classical Hindu gods Skanda and Hanuman.[31] In the later story of the origin of Ayyappa, Shiva impregnates Mohini, who gives birth to Ayyappa. Another variant says that instead of a biological origin, Ayyappa sprang from Shiva's semen, which he ejaculated upon embracing Mohini.[32] Ayyappa is referred to as Hariharaputra, "the son of Vishnu (Hari) and Shiva (Hara)", and grows up to be a great hero.[33] Another tale says after Surpanaka's destruction, Shiva wishes to see Mohini and mesmerized by her looks, has union with her resulting in the birth of Ayyapppa.[20]
