Vatsara married Svarvīthi, who gave birth to Puṣpārṇa, Tigmaketu, Iṣa, Ūrja, Vasu, and Jaya.
Vyuṣṭha married Puṣkariṇī, and gave birth to Sarvatejas, who had a son – Cākṣuṣa Manu, from his wife Ākūti.
[3][4] The Padma Purāṇa mentions that Sunīthā is the ugly daughter of Mṛtyu (death), and hence Vena is regarded to have been wicked from birth.
The Padma Purana states that Sunitha, Vena's mother, was a cruel woman, who enjoyed hurting other people.
The son, from his childhood, was attached to his maternal grandfather Mrityu (a portion of Adharma), and turned to unrighteousness.
Unable to disciple his child, Anga lost his peace of mind, and left his kingdom in disgust, retiring to the forest.
Fearing anarchy and thieves, the sages and the people crowned Vena as the king, even though they were dissatisfied with the prince.
However, Vena proclaimed that in his kingdom, no one would perform a sacrifice, and that they would not spend a single coin on religious acts.
The sages visited Vena's court to conciliate the king, offering him wisdom about dharma (duty), moksha (salvation), and his responsibility as a ruler from the Dharmashastras.
Angered by the insult that the king had made towards their Brahmin birth, and the deity Vishnu, the sages slew him with consecrated blades of grass, while uttering the huṃ sound.
[10] The sages then began to knead the corpse’s right hand, from which a shining man, Prithu, bearing a divine bow, arrows, and armour appeared.
The people sought out Prithu, informing him that during the anarchy before his accession, the world had become so gloomy and dark that the earth-goddess, and incarnation of Lakshmi, Bhumi, had decided that she would not provide crops to humans anymore.
