B1C1V5

B1C1V5: In normal course dying of a creature is the end of its use as a living being. So THE GOD of DEATH always gets the things which has no use as a living being. Nachiketa is contemplating that he is very good at some things and mediocre at some but not bad at any thing, so how he would be useful to THE GOD of DEATH. From hereon he is becoming serious living all of his childish inhibitions making him worth visiting Yama THE GOD of DEATH.

B1C1V4

B1C1V4: Nachiketa thinks that he himself is a precious possession of his father and should also be sacrificed. So naïve he is that he is curious to know that as an offering, to whom his father would give him. To his father, the proposition itself is so bogus that it is not worth responding. This proposition, on the other hand, is very much rational and obvious to Nachiketa. Father got irritated with his repeated stupid question because no common person can plan to sacrifice his own children as a part of a YAGGA. So irritated he is that he tells his son that he will offer him to DEATH.

B1C1V3

B1C1V3: What he is seeing and thinking is that the condemned and unusable things are being offered. Had the offerings take a person to Heaven, the quality of the goods being offered, would rather take a person to a place of unhappiness. Because this action proves that the person doing this is not a broad minded one. The main flair of the sacrifice is to grow detachment about the things sacrificed but here just the reverse is happening. The attachments to the things are so high that the person doing the YAGGA is not being able to get rid of involvement with the things sacrificed. Unless an aversion from the materialistic things have been achieved, this YAGGA if fruitless.
