The gnostic student will stand up facing east, lifting his left arm as indicated in the figure of the Rune Kaum. Breathe rhythmically and vocalize the mantra “KAUM”, like this: KAAAAAUUUUUMMMMM…
Samael Aun Weor
Esoteric Treaty of Runic Magic, Chapter 34
NOTE: The primitive Gnostic tradition indicates that the left arm must be raised to 45º with respect to the floor, and that the palm of the hand must face downward.
