Face each direction with your arms initially crossed, right over left, placed above your heart.
You can cover your solar plexus with your left hand and form the Gnostic pentagram with your right hand out (thumb, middle, and index fingers extended; the other two fingers clasped within the palm).
Perform the exorcism for each direction with their corresponding mantra: IAO for the North (earth), an exhalation of breath for the East (hhhhhhh... air) S for the South (fire), and M for the West (water).
For thirty years I sought God. But when I looked carefully I found that in reality God was the seeker and I the sought. -Bayazid al-Bastami
