On the one hand, our ancestors employed speech for the needs of their day-to-day life, and for communicating with one another just as we do; but, on the other hand, we know today that they attributed an incomparatively higher value to the word that was thought within and to the word that was spoken outside than we do today.

Therefore, the art of poetry was the high skill of our ancestors, and it was so intimately interwoven with the creation of music that, from our present view, we can hardly separate the one from the other.

Creating speech, creating words, mastering the inner and outer process of articulation, self-realization related to it, self-control, and furthermore, mastery over the environment, were considered high ideals by our ancestors.

Therefore, our ancestors were great creators of language, and their poetry is the gigantic testimony of this power. Their mastery over the process of self-cognition as well as over the principles of forming language is clearly reflected in the ancient records - no matter how incomplete they may be preserved.

Despite the ravages of time enough is left of the ancient records that even today we may still retrace the entire knowledge layed out in this book, provided we know how to read their symbols and interpret their explanations.
