Brahma manasaputras and there children
Once Bhishma asked sage Pulastya about the four prominent caste and Brahma's manasaputras.
This way, the first human pair-Manu and Shatarupa came into existence. In course of time four children were born to them---Priyavrata, Uttanapada, Prasuti and Aakuti. Prasuti was married to Daksha Prajpati, while Aakuti became the wife of Ruchi-Prajapati. Prasuti gave birth to 24 daughters-- Shraddha, Laxmi, Dhriti, Pushti, Tushti, Medha, Kriya, Buddhi, Lajja, Vapu, Shanti, Keerti, Khyati, Sati, Sambhuti, Smriti, Preeti, Kshama, Santati, Ansuya,Urja, Swaha and Swadha. Out of them, the former thirteen were the wives of Dharma and the rest were married to various sages like Bhrigu, Shiva, Marichi, Angira, myself (Pulastya), Pulaha, Kratu, Atri, Vashishtha Agni, etc. Shraddha gave birth to 'Kaama', Laxmi to 'Daarpa, Dhriti to Niyama, Tushti to Santosha, Pushti to Lobha, Medha to Shruta, Kriya to Danda, Naya and Vinaya, Buddhi to Bodha, Lajja to Vinaya, Vapu to Vyavasaya, Shanti to Kshama, Siddhi to Sukha and Keerti gave birth to Yashas. All of them were the sons of Dharma.
Kaama had a son named Harsha from his wife Nandi, Bhrigu's wife Khyati gave birth to a daughter named Laxmi--the consort of Lord Vishnu. Lord Rudra accepted Sati--the daughter of Daksha Prajapati as his wife. Himsa was the wife of Adharm and gave birth to Anrita and Nikriti. Anrita had two sons---Maya and Naraka, while Nikriti had two daughters--Maaya and Vedana. Maaya married Maya while Vedana became the wife of Naraka. Maaya had a son named Mrityu--the lord of death and Vedana gave birth to Dukhha. Five children were born to Mrityu--Vyadhi, Jara, Shoka, Trishna and Krodha. All of them were celibates and had no progeny.
