-Removed-That's not quite true.There are many different aspects of Vedic lterature. They cover not only religon and philisophy, but a great range of everyday-life teachings. Not all of which you have to be "intelligent" to understand. There are many everyday, simple tachings such as in the areas of health/medicine, agriculture,etc.
-Removed-Yourself and FMF have totally misunderstood me. The upanishad uses the words " intelligence " and " intelligent people " as that quality of those who are not misled by the manifest reality. Those whose curiosity is like Nachiketa's curiosity. Nothing to do with the IQ of any poster here. Let us not create issues where there are none. Pl.give a thought to what is contained in the story.
