Ancient Sages appreciated the power of sounds in languages. Many religions still conduct masses in Latin, rituals and ceremonies using extinct languages - because the ancient sounds are considered sacred.
Some believe that as civilizations changed so did their languages, which in a subtle way brought about mental, emotional and physical changes to people - because they were exposed to different sounds.
As man "involved" into matter throughout the ages... he became further into the experience of duality and further away from God. Therefore, extinct languages create sounds in which man was closer to God and not as immersed into the experience of duality. That is why the language of Sanskrit is referred to as an ancient language of light. That is also why some people find that listening to a Catholic mass in Latin feels holy. The sounds of the language have an impact on the people who hear it. It is not the meaning of the words, but the energy of the sounds that is important.
Different intervals, phonemes, and combinations of vowel sounds create different harmonics and precise subtle impacts on the body...changing the information (in the form of brain waves, emotions and impact on your physical body) that your body is exposed to. Notice that the people who speak oriental languages have general population characteristics that are different than people who speak African dialects! One impact on these civilization is the sounds they create with their own voices!
The ancient languages of light were said to be more powerful than today’s languages, as their sounds and the things they symbolized were identical. Today our languages are more symbolic. In a way this is good, as people can do less damage with hurtful words, in a symbolic language versus a language of light.
