"By the by, I may tell you that the idea of hell does not occur in the Vedas anywhere. It comes with the Purânas much later. The worst punishment according to the Vedas is coming back to earth, having another chance in this world. From the very first we see the idea is taking the impersonal turn. The ideas of punishment and reward are very material, and they are only consonant with the idea of a human God, who loves one and hates another, just as we do. Punishment and reward are only admissible with the existence of such a God. They had such a God in the Samhita, and there we find the idea of fear entering, but as soon as we come to the Upanishads, the idea of fear vanishes, and the impersonal idea takes its place."
