PURPORT

According to Vedic civilization, one gets married simply to have a son, who is needed to offer oblations to his forefathers. King Citraketu responsibly desired to beget a child so that he and his forefathers might be delivered from the darkest regions. He was concerned with how to get pinda, oblations, in the next life, not only for himself but also for his forefathers. Therefore he requested Aṅgira Rsi to favor him by doing something that could help him get a son.
