Once, the renowned sage Agastya, the illustrious husband of Lopāmudrā—himself born from a pot—approached Kumāra, the god Skanda, after worshipping him with devotion. Eager to learn, Agastya asked Skanda to recount various sacred stories. With great kindness, the blessed Skanda narrated many tales to Agastya, stories abundant in the glory of charity, holy places, and spiritual vows. Among these, he described in detail the supreme sanctity of Vārāṇasī, the origin of the sacred Maṇikarṇikā, and the revered pilgrimage sites along the Gaṅgā. Deeply pleased by these accounts, Agastya, with a heart full of gratitude and concern for the welfare of all beings, again questioned Kumāra, who shone with radiant splendor. He addressed the Lord, saying, “O slayer of Tāraka, please tell me the proper way to hear the greatness of the Devī Bhāgavata.” Agastya continued, “This Purāṇa, called the Devī Bhāgavata, is supremely excellent, for in it the eternal Mother of the three worlds is directly praised.” To this, Skanda replied, “Who indeed can fully describe the greatness of the Śrī Bhāgavata in detail? Yet, O Brahman, listen as I briefly reveal its essence to you. She who is eternal, whose nature is existence, consciousness, and bliss—the Mother of the universe—is present therein, bestowing both worldly enjoyment and ultimate liberation. Therefore, O sage, the Devī Bhāgavata is truly the embodiment of Her divine speech; by reading or hearing it, nothing in this world is difficult to attain.” Skanda then began a tale: “There was once a son of Vivasvat, known as Śrāddhadeva. Though a king, he was childless, and so, under the guidance of the sage Vasiṣṭha, he performed a great sacrifice. His beloved wife, Śraddhā, prayed to the priest, ‘O Brahman, let a daughter be born to me; please arrange the means for this.’ The priest, following her wish, mentally offered a daughter in the sacrifice. Thus, through this unusual ritual, a girl named Ilā was born. When the king saw his daughter, he approached his guru with a troubled heart and asked, ‘O revered one, how has this discrepancy in intention come about?’ On hearing this, the sage reflected deeply, realized the priest’s error, and, desiring that Ilā should become male, sought refuge in the Supreme Lord. By the power of the sage’s austerities and the grace of the Lord, Ilā, before the eyes of all the worlds, was transformed into a man. Consecrated by his guru, the child—now known as Sudyumna, the son of Manu—became a repository of wisdom, just as the ocean is the gathering place of rivers. In the course of time, Sudyumna grew to youth and, mounting a Sindhu horse, ventured into the forest to hunt. Journeying from one forest to another with his retinue, fate led Sudyumna to a forest at the foot of Mount Hemadri. At that very moment, the god of gods, Shankara (Shiva), was there, delighting in the company of his wife Aparna (Pārvatī). Meanwhile, sages, longing for a vision of Shiva, arrived at that place. Seeing them, Girijā (Pārvatī) became bashful. The sages, witnessing Shiva and his consort in their intimate joy, withdrew respectfully and departed to Vaikuntha. Desiring privacy with his beloved, Shiva pronounced a curse upon the forest: ‘From this day, any man who enters here shall become a woman.’ From that time, men avoided the region. Yet Sudyumna, unaware, entered and was instantly transformed into a beautiful woman. Astonished, Sudyumna saw that his horses had become mares and his followers had also become women. Now a lovely woman, she wandered from forest to forest. One day, she came near the hermitage of Budha, the son of Soma. Budha beheld her—her limbs graceful, her breasts full and high, her lips like bimba fruit, teeth like jasmine buds, her face radiant, and eyes like lotuses. Struck by the arrows of love, Budha desired her. She, too, with enchanting brows, was drawn to Budha. Thus, she remained in his hermitage, delighting in his company. In time, Budha, born of Mitra and Varuṇa, fathered a son with her—Pururavas. After some years, memories of her former life as a man awakened in her heart, filling her with sorrow. She left Budha’s hermitage and went to her guru Vasiṣṭha, bowed before him, recounted all that had happened, and sought his help to regain her manhood. Vasiṣṭha, understanding her plight, journeyed to Mount Kailāsa. There, he worshipped Shambhu (Shiva) and praised him with utmost devotion: “Salutations, salutations to Shiva, to Shankara, the matted-haired one; to him whose body is half united with Girijā, to the moon-crested one, I bow. Salutations to you, giver of happiness, gracious Lord of Kailāsa, blue-throated one who grants enjoyment and liberation to devotees. Salutations to Śiva, of auspicious form, remover of fear for those who seek refuge, bull-rider, shelter of all, supreme self. Salutations to you who are Brahmā, Viṣṇu, and Īśa in creation, preservation, and dissolution; god of gods, granter of boons, destroyer of Tripura. Repeated salutations to you, embodiment of sacrifice, giver of its fruits, bearer of Gaṅgā, whose hair, sun, moon, and fire are your eyes.” Thus praised, the blessed Lord, master of the universe, appeared before Vasiṣṭha, mounted on a bull and accompanied by radiant Ambikā (Pārvatī), shining with the brilliance of millions of suns. He resembled a silver mountain, three-eyed, adorned with the crescent moon. Pleased, he addressed the sage who had bowed before him: “Choose a boon, O best of sages, whatever is in your heart.” Vasiṣṭha requested the restoration of Sudyumna’s manhood. The gracious Lord replied: “For one month you shall be a man, and for one month a woman.” Thus, by the grace of Shiva and the devotion of his guru, Sudyumna’s unique destiny was set, and the story of his transformation became woven into the sacred lore, as recounted by Skanda to the wise Agastya.
