Devi

'Formerly, Bhagavati, being pleased, killed Mahishasura. When praised by you, the Devi then granted a boon.'

The gods said: Salutations to Shivaa, Kalyani, Shanti, and Pushti; salutations again and again! Salutations to Bhagavati, the Goddess; constant salutations to Rudrani!

'...whoever comes forward to support her, must be swiftly killed by you. Kill the Kali standing by her side, and then capture her (Ambika)...'

Thus praised by the twice-born, the Goddess Mahāmāyā—intent on slaying Karṇāṭa and securing the welfare of the dvijas—manifested there in visible form and said, “Speak your boon.”

Then, endowed with firm faith, she worshipped properly—having installed the Goddess Ambikā, the sovereign Lady of the gods, there (in that sacred place).

There is the chaste queen Sīmantinī of the king of Niṣadha; on Mondays she worships Mahādeva together with Ambikā.

Nārada said: “O Brahman, O greatly wise one—after hearing the entire account of those events, tell me truly: what did Mahādevī do? I wish to hear it in accordance with the real principle (tattva).”

Placing her—who abides on the northern shore of the Kṣīroda—within his own heart, he began to perform austerities, desiring to behold Ambikā directly, face to face.

Hearing my words, “Speak your boon,” you chose that very boon: “O Mahādevī, become my daughter; and by that, accomplish what is beneficial for the gods.”

Then, seeing that the great king—self-controlled—was firmly resolved at her lotus-feet, Ambikā, well-pleased, manifested herself directly.

She, whose very nature is both being and non-being, the eternal cause of the universe, suddenly became threefold—as Brāhmī, as Lakṣmī, and as Ambikā.

"By my boon, your penis shall become (like) a ram’s testicle." Having said this, the Mother of the world disappeared right there.
