It is interesting to note that most of the very very early scriptures were passed down through generation after generation by word of mouth and not in writing--not only scriptures, but also mythological histories and chants. This shows that those earlier races, or rather peoples, had a prodigious capacity to keep hold of statements and not to forget them. Why is it that has mostly disappeared among us today? The reason is the same one that explains why the primitive peoples were closer to nature, were much more psychic, more aware of the psychical planes. And that reason is that the logical intellect has since then been developed and has replaced, to a certain extent, the instincts, clairvoyance, and so on.
