In ancient times, the seven vowels of Nature: I E O U A M S resounded within the human organism. But, when humanity came out of the “Jinn” lands, rhythm and harmony were lost.
Therefore, the human being must be aware of the urgent necessity for the seven vowels of Nature to vibrate once again within the organism; they must resound with intensity within the resonating internal chambers, as well as in each of the plexus or chakras of the Astral Body.
The frontal chakra is developed with the intonation of the vowel I pronounced like this: Eeeeeeeeeeeeeeeee (as in “coffee”).
Clairvoyance is developed with the vowel I.
The larynx chakra is developed when chanting the vowel E like this: Eh (like “egg”). Clairaudience the magic ear is awakened with the vowel E.
The cardiac chakra is developed while vocalizing the vowel O like this: Oooooooooooooooooooooooooo (as in “Oh”). Faculty: Intuition, astral projections. The heart center develops inspiration and is developed with the vowel O.
The umbilical chakra is developed by intoning the vowel U like this: Uuuuuuuuuuuuuuu (as in “you”). Faculty: Telepathy.
The pulmonary chakra is developed by singing the vowel A like this: Aaaaaah (“Ah”). The pulmonary chakra allows us to remember past reincarnations and is developed with the vowel A.
The vowels M and S make all of the internal centers vibrate.
These vowels combined with certain consonants integrate the mantras that facilitate the awakening of all the chakras.
I.E.O.U.A.M.S. is the order of the vowels. All of the mantras are formed with these letters.
Dr. Krumm-Heller stated that one hour of daily vocalization is better than reading a million books of pseudo-esotericism and pseudo-occultism.
I would then inhale with supreme eagerness the Christonic Prana, the vital breath of the mountains, and then I would slowly exhale while making the resounding of the correspondent vowel.
For better clarity, I state that each vowel was preceded by an inhalation and was only resounding in the exhalation (it is obvious that I was inhaling through the nostrils and exhaling through the mouth).
