This is continuation after Matsyavatar. In new Cosmic cycle, Lord Brahma wanted to start creation again. But on seeing that in spite of all his creations the population was not increasing, he decided to create his Manasputras. These Manasputras were created merely by his wish. Their names were Bhrigu, Pulastya, Pulaha, Kratu, Angira, Marichi, Daksha, Atri and Vashishta. As Daksha was born from Brahma's thumb, he was strongest of all. After this, he created Sankalpa and Dharma. But all these people were very virtuous, knowledgeable and unaffected by worldly desires. They showed their disinclination towards the purpose for which they have been created by Brahma i.e. increasing the population. Brahma became very furious in his anger and created an entity whose half portion resembled a man's body while the remaining half resembled that of a woman.
Brahma instructed that entity to bisect his body into two distinct forms of a man and a woman. The entity followed Brahma's instruction and this way Swayambhu Manu and Shatrupa came into being. Manu accepted Shatrupa as his wife. Two sons and two daughters were born to them- Priyavrata, Uttanpada and Akuti, Prasuti. Prasuti was married to Daksha. 1000 sons and 50 daughters were born to Daksha and Prasuti out of which thirteen daughters were married to Kashyap who is the son of Marichi.
Kashyap got his family from his 13 wives. His important family lines are stated below
1. From Diti, he got Hiranyaksha and Hiranyakashyapu. whose family line is called Daityas.

After some thousands of years, Vishnu came before him saying that he incarnated from his navel. Brahma was unwilling to believe this as he was thinking that he is the first being created in universe. They started quarreling about who is Superior among them. Then suddenly a form of a column of light, appeared beside them. The column seemed to have no beginning or end, stretching upwards and downwards as far as the eye could see. The two gods decided that whoever found the top or the bottom of the column first would be deemed to be superior to the other.
