B1C1V7:

After reaching the house of YAMA, Nachiketa had to waiting for YAMA for three days, because YAMA was not present. While waiting he declined all request for food & drinks, because he did not know how the owner of the house would accept him. The inmates of the house of YAMA could understand that the kid was in search for the absolute truth and so he was most adorable and respectable person to them. That is why, when YAMA came, the inmates of his house told him to extend a gesture of hospitality and respect to the guest. A seeker of truth deserved to be treated most respectfully. He is like fire, so to calm him down one should extend his respect and hospitality to him just as one calms down the fire with water.

B1C1V6: Father was not serious about the sacrifice of his son to YAMA – THE GOD OF DEATH, but Nachiketa is. He is consoling his father by saying that we have to look back as well to look forward too and considering the situation dispassionately we should step accordingly. Death too should not scare one from doing what is ought to be done. Life is a continuous process. All living thing born and grow and die and rot. So meeting the death one day is inevitable so not a big deal to Nachiketa.
