Srimad Bhagavatam Canto 04, Chapter 08, Text 02

SB 4.8.2

mrsadharmasya bharyasid
dambham mayam ca satru-han
asuta mithunam tat tu
nirrtir jagrhe ’prajah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Another son of Lord Brahma was Irreligion, whose wife’s name was Falsity. From their combination were born two demons named Dambha, or Bluffing, and Maya, or Cheating. These two demons were taken by a demon named Nirrti, who had no children.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
It is understood herein that Adharma, Irreligion, was also a son of Brahma, and he married his sister Mrsa. This is the beginning of sex life between brother and sister. This unnatural combination of sex life can be possible in human society only where there is Adharma, or Irreligion. It is understood that in the beginning of creation Brahma created not only saintly sons like Sanaka, Sanatana and Narada but also demoniac offspring like Nirrti, Adharma, Dambha and Falsity. Everything was created by Brahma in the beginning. Regarding Narada, it is understood that because his previous life was very pious and his association very good, he was born as Narada. Others were also born in their own capacities, according to their backgrounds. The law of karma continues birth after birth, and when there is a new creation, the same karma comes back with the living entities. They are born in different capacities according to karma even though their father is originally Brahma, who is the exalted qualitative incarnation of the Supreme Personality of Godhead.
