Whosoever wants to become clairvoyant must reconquer the lost infancy.
The atoms of infancy live submerged within our internal universe and there is the necessity of putting them afloat again in order to attain divine clairvoyance. This labor can be performed by means of the verb. Therefore, the following mantras must be pronounced:
These mantras must be sung by raising the tone of the voice with the first syllable of each word and descending the voice with the second syllable of each word. Then, the child who lives submerged within us emerges to existence again, and we become clairvoyant.
This teaching was delivered to me by the Angel Aroch, for the disciples. These exercises of vocalization must be practiced daily.
