Standing in a straight position, let us raise our arms in order to form a straight line with the whole body, and after praying and asking for help to our Divine Mother we must sing the Mantra ISIS, as follows: IIIIIIIIISSSSSSSS….IIIIIIIIIIISSSSSSSSSS. Prolong the sound of the two letters and divide the word in two syllables IS-IS. [Sounding of the letter I is similar to that found in the word “tea”]
Afterward, the student must lay down with his relaxed body and filled with ecstasy must concentrate and meditate on the Divine Mother.
