Mystical sounds in which there is alleged to be astonishing power is part of the Jewish Kabbala oral teaching. They are considered to be so powerful that they have never been put in writing - as the tradition goes - and have existed from Adam, passed down orally from generation to generation to a very select and trusted few members of the Jewish Kabbala.
As I recall, none of the three ancient Enoch manuscripts speak of such sounds.
Very important: the Jewish Kabbala should not be confused with the New Age Kabbala which has "hijacked" the ancient Jewish tradition and ancient manuscripts such as Enoch to support their mysticism.
All of the ancient manuscripts in the pseudepigrapha are however very informative - at the minimum concerning the thinking at the time and geopolitical location of their writing. But as always, Spiritual truth can only be revealed by the Spirit Himself.
Also very important: the versions of Enoch available online are very often associated with the new age websites and use older translations which are incorrect (e.g. without information gathered from the Dead Sea Scrolls) and/or lack the scholarly footnotes necessary to understand the ancient language and how/why things were translated a certain way, dating, etc.
For a good source of pseudipigraphal manuscripts translated to English: Volume 1 and Volume 2.
Thanks.
I knew I could count on you to put a more solid truth and Biblical perspective on things.
Much appreciated.
