Nabhaga's father said: All the descendants of Aṅgira are now going to perform a great sacrifice, but although they are very intelligent, on every sixth day they will be bewildered in performing sacrifice and will make mistakes in their daily duties.
Nabhaga was very simple hearted. Therefore when he went to his father, the father, in compassion for his son, suggested that as a means of livelihood Nabhaga could go to the descendants of Aṅgira and take advantage of their misgivings in performing yajna.
