The following, in quotations, is taken from the Cicero's "Self Initiation into the Golden Dawn Tradition' as published by Llewellly Publications. The graphic used is also from this source.

"(This exercise can be performed either standing, sitting, or lying down.) After a few minutes of relaxation, imagine a sphere of white Light just above your head. Vibrate the name "EHEIEH" (I am). Keep vibrating this work until it is the only thought in your conscious mind. Then imagine a shaft of light descending from your Kether center to your Daath center at the nape of the neck. Form a sphere of Light at the Daath center. Vibrate the namd "YHVH ELOHIM" (The Lord God). Intone the name until it is the only thing in your conscious mind. Bring a shaft of Light down from the Daath center to the Tiphareth center around your heart. Form a sphere of Light there. Vibrate the name "YHVH ELOAH VE-DAATH" (Lord God of Knowledge) several times until it fills your consciousness.

See the shaft of Light descending from Tiphareth into the Yesod cender in the genital region. Imagine a sphere of Light formed there. Intone the name "SHADDAI EL CHAI" (Almighty Living God) several times.

Visualize the shaft of Light descending from Yesod into your Malkuth center at the feet and ankles. Vibrate the name "ADONAI HA-ARETZ" (Lord of Earth) a number of times as before.

Imagine the Middle Pillar Complete. Then circulate the Light you have brought down through the Middle Pillar around the outside of your body to strengthen you aura. Using the cycles of breathing, bring the Light up one side of the body and down the other, from Malkuth to Kether and back again. After performing this for a short period of time, imagine the ribbon of Light descending down the front of your body and rising up your back.

Still employing rhythmic brething, visualize the shaft of Light rising up the Middle Pillar in the center of your body. When it reaches Kether, imagine a shower of Light surrounding the outside of your body as it descends to Malkuth again. Circulate the Light in this manner for some time. Then see the Light rise again in a ribbon that spirals round the outside of your body.

Finally focus some of the energy back into your Tiphareth center, the seat of equilibrium and balance.

You may decide to end the exercise with the Qabalistic Cross to indicate that you have called down the Light of your Kether and balanced it in your aura. Then let your imagination dwell on the aura and see it oval and clear, pulsating withthe glow from Tiphareth. (Note: this simple exercise of Middle Pillar is the basis for many complex formulas of magic.)"

Personal comment:
One thing the reader will notice in the above is the lack of color when using this form of the Middle Pillar exercise. It is the present writers belief that it is of some importance to the practitioner to build up the performance of this exercise gradually, beginning with utilizing the visual imagination to formulate the spheres in white Light only. After several weeks of performing this ritual with only the visualization of white Light, the student may then wish to begin utilizing the colors of the spheres while performing this ritual. These colors are as follows:
