RITUAL OF THE MIDDLE PILLAR
1. Stand with your hands at your sides, eyes closed, steady relaxed breathing and your mind calm and still.
2. Just above your head, visualize a sphere of clear light. Know that this sphere embodies the source of all potential. Vibrate the God name Eheieh (Eh-Heh-Yeh) 7-21 times. The sphere should begin to feel stronger and stronger.
3. Now visualize a slender beam of light descending from the brilliance through the center of your head, and stopping at the nape of your neck. Here the beam widens into a ball of light, although not as big as the one above. At this point you should be visualizing simultaneously the brilliant sphere above your head, the small ball of light at the base of your neck, and the beam of light connecting the two. Know that this is the link between your human consciousness and your higher self, and the ball of light at your neck should grow in size and intensity.
Vibrate the God name YHVH Elohim (Yod-Heh-Vav-Heh Eh-Loh-Heem) 7-21 times.
4. Keeping the above in mind, cause a beam of light to descend from the ball of light at your neck, go down your torso, and light up the breast\heart in the form of a sphere. Briefly contemplate this as your Consciousness, and the ball should increase in brightness and intensity. You may feel as if you are being warmed by an internal sun.
Vibrate the God name YHVH Eloah Ve Daath (Yod-Heh-Vav-Heh Ehl-oh-ah Vah-Ah-Dah-aht) 7-21 times.
5. In the same manner, see the light descend to the area of the genitals and form a sphere. Here, regard yourself as master of your "lower self". The Divine name to be vibrated 7-21 times here is Shaddai El Chai (Shah-dye Ehl Chai).
Note: The “ch” should be like in the Scottish word“Loch”, while the word “Chai” rhymes with “eye”.
6. Again the ball of light should descend, here to form a sphere which encompasses both feet and the ground; that is, the sphere should be half above ground, covering the feet, and half below the ground, under the feet, connecting ti the middle of the Earth: The God name to be vibrated 7-21 Times is Adonai Ha-aretz (Ah-doh-nye Hah- Ahr-etz).
7. At this point there should be large spheres of light above the head, at the throat, at the solar plexus, at the groin and at the feet. Each sphere of light should be connected with the sphere above and below by a beam of light.
8. Stay in this state for as long as you desire.
Then I amended the Ritual using the Hindu Divine Names Ov each Chakra 7-21 times each and bring the Chi back up using :
LAM - Root - Red Ligh
VAM - Sacral - Orange Light
RAM - Solar Plexus - Gold Light
YAM - Heart - Green Light
HAM- Throat - Blue Light
AUM - Third Eye and Crown - Blinding White Light
Then, take a deep breath, and start the Circulation of The Light, as the Light you have just invoked into all spheres and chakras of the Body, condense as a large body of light that you start to control with visualization and the breath. As you inhale, the light goes up the spine and on the exhale goes down the front of you, after 3-7 circulating currents, the rhythm switches to the light descending down the spine on the exhale and coming up the front on the inhale. After 3-7 times, the light switches to going down the left half of the body on the exhale and up the right side on the inhale then after 3-7 times, the order is reversed and the light goes down the the right side on exhale and up the left on the inhale. To end the Ritual Ov The Middle Pillar, the Light starts to come up the whole body from the feet on the inhale and at the crown of the head, the light showers out in all directions on the exhale and this is done 3-7 times. The Qabalistic Cross ends this powerful ritual that should be done once in the morning after the Lesser Invocation Ritual Ov the Pentagram and at night, after the Lesser Banishing Ritual Ov the Pentagram.
