Burned by the overwhelming radiance of the Sun, Martanda, the mighty asuras were reduced to ashes. In that moment, all the dwellers of heaven rejoiced as never before, their joy unparalleled. They praised Martanda, the very source of light and energy, and also honored Aditi. Through their gratitude and worship, the gods regained their rightful domains and their shares of the sacred sacrifices, just as in times past. Martanda himself then assumed his own dominion. Surrounded above and below by rays clustered like kadamba flowers, he shone brilliantly, resembling a mass of fire, though his form was not yet fully distinct. At this, a question arose: "How did the Sun later obtain a form even more beautiful, shaped like a perfect sphere of kadamba blossoms? Please tell me, O Lord of the world." In response, it is said that Tvashtar, the divine artisan, having propitiated Vivasvat with reverence and humility, gave his daughter Samjna in marriage to him. The lord of cattle, Vivasvat, begot three children with Samjna: two sons of great splendor and a beautiful daughter named Yamuna. But the radiance of Martanda Vivasvat was so intense that it scorched the three worlds, affecting all beings, both moving and unmoving. Seeing this form of Vivasvat, shaped like a brilliant sphere, Samjna found herself unable to endure his searing light. She spoke to her own shadow, Chaya, saying, "Blessings to you. I shall go to my father's abode; you must remain here unchanged, by my command, O auspicious one. These two sons and this daughter are to be considered mine; you must never reveal this to the Lord." Chaya replied, "O goddess, from the time of the hair-grasping until the curse, I shall never tell your decision. Go wherever you desire." Thus, abashed, Samjna departed for her father's house and dwelt there for a thousand years. Even as her father repeatedly urged her to return to her husband, Samjna transformed herself into a mare and journeyed to the land of the northern Kurus. There, that virtuous one performed severe austerities, abstaining from all food. Meanwhile, Chaya, intent on fulfilling Samjna's command, remained in her place, assuming Samjna's form and approaching Bhaskara, the Sun. The blessed Sun, believing her to be his true wife, was with her. In the same way, he begot two sons and a daughter with Chaya. However, Samjna, from afar, made those children earthly beings. Chaya did not show the same affection to these later children as she did to the former ones. Manu, one of the sons, forgave her, but Yama, the other, did not. Greatly afflicted by both his mother and father, suffering intensely, Yama, in his anger and childishness and compelled by fate, threatened his mother with his foot, though he did not actually strike her. Because of this, Chaya pronounced a curse upon him: "Because you threatened your father's wife, who is most venerable, with your foot, therefore this foot of yours will fall—there is no doubt." Troubled deeply by this curse, Yama reported everything to his father Manu, a righteous soul. "O god," he said, "our mother does not show equal affection to us; forsaking the elder, she wishes to favor the younger with devotion. My foot was only raised against her, not placed on her body. Whether from childishness or confusion, you should forgive this, lord. I have been cursed by my mother in anger, for I am her son; therefore, O best of ascetics, I do not consider her my true mother. By your grace, O lord, may my foot not fall as a result of my mother's curse today; consider this, O protector of the earth." Manu replied, "Without doubt, my son, there is a great reason for this, by which anger entered you, who know and practice righteousness. There is indeed a remedy for all curses, but for those cursed by their mother, there is nowhere any reversal. It is not possible to make your mother's words false; yet, out of affection for you as my son, I will grant you some favor. Worms will take the flesh and depart to the earth; thus, her words will be fulfilled in truth, and you shall be protected." The Sun then questioned Chaya: "For what reason, among your children who are equal, have you shown greater affection to one? Surely you are not their true mother; some other identity has come to you. Even among children without qualities, a mother does not give a curse." Fearful of the consequences, Chaya sought to avoid the curse and finally confessed the truth to the Sun. Hearing her words, the Sun went to his father-in-law, Tvashtar. Tvashtar, after honoring the Sun, who was now burning with anger, spoke to him soothingly: "This form of yours, pervaded by excessive radiance, is extremely difficult to bear. Unable to endure it, Samjna wanders in the forest, practicing austerity. Today you will see your virtuous wife, performing great penance in the forest for the sake of your form. I have heard Brahma's words regarding the restraint of your radiance; today, O lord of the day, I will fashion a pleasing form for you." The blessed Sun agreed, saying, "So be it," and Tvashtar set to work. Thereafter, the form of Vivasvat became more refined. Visvakarman, the divine craftsman, having received permission from Vivasvat in Shakadvipa, began the process of diminishing the Sun's radiance by means of a whirling motion. The dazzling radiance, which could not be overcome even by the whirling of all worlds, spread upwards, touching earth, ocean, mountain, and sky. O sages, the entire sky, along with the moon, planets, and stars, was cast downward, becoming agitated and disturbed. All the oceans were churned and disturbed, and the great mountains, their ridges and bases shattered, were split apart by the force of this divine transformation.
