Lomaharshana said:
1. O excellent brahmins, Vivasvān was born of Dakshāyaņi and Kaśyapa. The gentle lady, the daughter of Tvastr named Samjña was the wife of Vivasvān.
2. That beautiful lady was well known in the three worlds as Sureśhvarī (goddess of Devas). She was the wife of lord Märtanda of great soul.
3. Samjñā had been endowed with fair complexion, beauty and freshness of youthful bloom. She was not satisfied with the complexion of her husband. She was endowed with penance that had made her brilliant and dazzling.
4. Since, Aditya’s limbs had been burnt by the refulgence of his disc, Aditya’s complexion did not appear to be very attractive.
5. Aditya is called Märtanda for the following reason:- Once unknowingly Käsyapa had uttered out of his filial affection “I hope he is not dead even as he lay in the womb.”
6. The refulgence of Vivasvän increased day by day whereby the son of Kaśyapa scorched the three worlds too much.
7. O brahmins, Āditya the foremost among those who scorched the earth begot three children of Samjñā, a daughter and two Prajapatis.
8. At the outset, Vaivasvata Manu, the Prajāpati known as Sräddhadeva was born. Yama and Yamunā were born as twins.
9. On seeing the dark-coloured Vivasvān, Samjñā could not bear it. Therefore, she created her own shadow known as Savarņa.
10-11. That illusory Samjñā arising out of her shadow bowed to Samjña. O excellent brahmins, with her palms joined in reverence she said - “O lady of pure smiles tell me. What shall I do for you. O fair-complexioned lady, I abide by your directives. Command me.”
Samjñā said:
12. “Welfare unto thee, I shall go to my father’s abode. Thou wilt unhesitatingly stay behind in my house.
13. These two sons of mine and this daughter of beautiful slender waist should be nurtured by thee. O splendid lady, never should this secret be divulged to our lord.”
Savarṇā said:
14. “O gentle lady, not until I am caught hold of by my tresses, never till I am threatened with a curse, will I divulge the secret. O gentle lady, obeisance to Thee. You shall go comfortably assured thus”.
Lomaharshana said:
15-17. Having commended Savarņā and having been assured by her saying. “So, it shall be” that lady in her pitiable state approached (her father) Tvaştr and stood by him bashfully. That splendid lady standing thus abashed near her father was rebuked by him. Again and again she was directed by him, saying “Go back to your husband”. Assuming the form of a mare and thereby concealing her beauty that blameless lady went to the northern Kurus and began to graze grass.
18-19. Taking the second Samjñā to be the real Samjñā, Aditya begot of her a son equal to himself in every respect. O brahmins, since he was on a par with his elder brother Manu, he too became Manu by name. He is called Såvarna (son of Savarņā) too.
20-21. The second son who was born of her was known as Sanaiscara. Samjñā, like an ordinary woman of Earth, loved her own sons more. She was not equally disposed to the elder ones. Manu forgave this weakness on her part but Yama did not.
22. Out of anger and childishness or may be due to the inevitability of what was destined to happen, Yama, the intrinsically careless son of Vivasvat lifted up his leg (as though to kick her) and threatened Samjñā.
23. The mother of Savarna, who became extremely distressed cursed him wrathfully-” May this foot of yours fall down”.
24. Extremely frightened and distressed due to the curse, and growing suspicious by the utterances of Samjña, Yama intimated everything to his father with palms joined in reverence.
25-27. “May this curse be averted” said he to his father, O brahmins. “A mother should be impartially affectionate to all her sons. O Vivasvān, she wants to remove us and she desires to become the sole beneficiary. Of course the foot was lifted up by me to her but it did not touch her, maybe due to my puerile whim, maybe due to my extreme desire, maybe due to my delusion-whatever that maybe—it behoves you to forgive me. O lord of worlds, O most excellent one among those who scorch, I have been cursed by my mother. O lord of rays, may my foot never fall off, I beg you favour”.
Vivasvān said:
28. In this matter, O son, there will undoubtedly be a great reason wherefore fury has stirred you who are conversant with righteousness and who (invariably) speak the truth.
29. It is impossible to falsify the words of your mother. Worms will take the flesh from your foot and it will fall off to the ground.
30. The words of your mother will be rendered truthful but you will be saved by avoiding the worse effects of the curse.
31. Aditya spoke to Samjña: — “How is it that more affection is shown to one when all sons are on a par with one another?”
32. Evading (a straight reply) she did not tell (the truth) to Vivasvat. He entered into self-meditation and found out the truth by his Yogic power.
33-35. O excellent sages, the lord was ready to curse her to destruction but she mentioned the truth to Vivasvan in the manner it had transpired before. On hearing the same, Vivasvat was infuriated and rushed to Tvaştr. On seeing Vivasvat, Tvaştr honoured him suitably. As the sun was about to scorch him in anger, he appeased him quietly.
Tvaştr said:
36-38. Affected by excessive refulgence this complexion of yours is not alluring. It was because she could not brook it. She is now grazing grass in the meadow in a forest. O lord of rays, by adopting Yogic power you will presently see your wife of auspicious conduct who is worthy of praise and who is endowed with Yogic powers. O lord ! O suppressor of foes, if my suggestion is approved by you I shall turn your complexion favourable to you. I shall make it alluring.
39. When Vivasvat agreed to the proposal Tvaştr mounted him on the lathe, whetted him and made his complexion sparkling.
40. Then his form became more dazzling due to the well knit refulgence. It was very alluring and he appeared very splendid.
41. Adopting his Yogic power be met his wife who had assumed the form of a mare. She could not be thwarted by any living being due to her observance of holy rites and her own brilliance.
42-43. The lord assumed the form of a horse and approached her as she grazed about fearlessly in the form of a mare. It was in her mouth that he had his sexual intercourse, as she began fidgeting due to her suspicion that he might be a person other than her own husband. She let out the semen of Vivasvat through her nostrils.
44-49. Two sons were born of her thus. They were Asvins who later became excellent physicians. They were known as Näsatya and Dasra. They were the sons of the eighth Prajāpati.
Bhaskara revealed his alluring form to Samjñā. O excellent sages, on seeing her husband in the attractive form she became delighted.
Yama was extremely distressed due to his activity. He delighted his subjects by his righteous conduct. He was known as Dharmaraja. Due to his righteous activities he became extremely brilliant and attained the lordship of Pitrus and status of the guardian of a quarter, O ascetics, Manu the son of Sāvarna is the future Prajāpati in the Sävarņika Manvantara. Even today he is performing penance on the top of Meru.
50-54. His brother Sanaiścara attained the status of a planet. With that refulgence (of Aditya) Tvastr evolved the discus of Vishnu for destroying the Asuras. The weapon is never thwarted in a battle. The youngest daughter Yami became the famous excellent river Yamuna who sanctifies the world. The brother is called Savarna Manu. The second son, the brother of Manu, became Sanaiścara, the planet saturn, honoured in the world. He who listens to this narrative on the origin of Devas and retains the same in his memory will attain great fame. Even when involved in adversities he will be liberated therefrom.
Summary of chapter 4 of the Brahma Purana is as follows:
The origin and evolution of Vivasvat (the Sun-god, Āditya) are narrated, tracing his birth from Kaśyapa and Aditi. The chapter describes how Vivasvat came to be recognized as the luminous lord of the solar world, his relationship with Saṃjñā (his wife, daughter of Viśvakarman), and the significant progeny born from their union — including Vaivasvata Manu, Yama, and Yamī.
