All the great beings who were responsible for creation of living beings are called Prajapati in Hinduism. They are all the sons of Lord Brahma. With all severe austerity, penance, worship, trance and bhakti yoga Lord Brahma created Maharishis who came to be known as Prajapatis.
This Episode of Holy Tales by Himanshu Sharma will tell you the story of Kardama Muni who was also a Prajapati and directly born from the body of Brahma. A Rishi who was so involved in Bhakti that he even forgot that he was married.
