The Fulmen Gnostica - The Gnostic Thunderbolt

Inhale.

Starting just beyond the head, draw the first point of the Thunderbolt.
Visualize yellow sphere emblazoned at the top of the head, and send a thread of light to the point.
Vibrate "iiiiii..." in a high-pitched tone until the lungs are emptied.

Inhale.

Trace a straight line from top of head to left hip.
Visualize a purple sphere lighting up, sending a thread of light to the second point.
Vibrate "eeee..." in a slightly lower tone.

Inhale.

Trace a second line from left hip to right shoulder.
Visualize a orange sphere illuminating, sending its light to the third point.
Vibrate "oooo..." in a tone lower than the previous vibration.

Inhale.

Trace a third line from right shoulder to feet.
Visualize a black sphere encircling the feet, disappearing into the ground, and sending its thread to the fourth point.
Vibrate "uuuu..." in a lower tone.

Inhale.

Trace the fourth line from feet upwards to the left shoulder.
Visualize a orange sphere lighting up, sending its light to the fifth point.
Vibrate "eeee..." in a lower tone.

Inhale.

Trace the fifth line from the left shoulder to the right hip.
Visualize a purple sphere which sends its light to the sixth point.
Vibrate �aaaa...�

Inhale.

Trace a line from the right hip to the solar plexus.
Visualize a orange sphere illuminating the seventh point and within it a pentagram either obverse or inverse as you prefer.
Vibrate �oooo...�

Notes:
Remain completely motionless and hold your breath for as long as possible. Concentrate your attention fixed on the sound of your blood rushing through your carotid arteries. Visualize the earth energies rising to the crown. Know that the rumbling you hear is the eternal explosion of the Thunderbolt. You are part of the thunderbolt moving endlessly and mindlessly onward.

Continue to hold the image and sound in the mind while holding your breath. When you finally must breathe, envision the thunderbolt fragmenting with a tremendous roar and sending octarine sparks into and through you.

Repeat the seven steps above, drawing the thunderbolts about you to describe a 3-dimensional shape of whatever kind suits you.

Declaration of intent, i.e. "We will that we never end where we had begun. We will that we shall begin."

Important Note:
The pronunciation of the vowels must be performed accurately in accordance with Gnostic tradition. Each vowel is vibrated 22 times. The formula of 22 divided by 7 leaves you with the letter Pi.

The Gospel of the Egyptians refers to the formula thus:
Domedon Doxomedon came forth, the aeon of the aeons, and the throne which is in him, and the powers which surround him, the glories and the incorruptions. The Father of the great light who came forth from the silence, he is the great Doxomedon-aeon, in which the thrice- male child rests. And the throne of his glory was established in it, this one on which his unrevealable name is inscribed, on the tablet [...] one is the word, the Father of the light of everything, he who came forth from the silence, while he rests in the silence, he whose name is in an invisible symbol.
A hidden, invisible mystery came forth:
iiiiiiiiiiiiiiiiiiiiii
EEEEEEEEEEEEEEEEEEEEEE
oooooooooooooooooooooo
uuuuuuuuuuuuuuuuuuuuuu
eeeeeeeeeeeeeeeeeeeeee
aaaaaaaaaaaaaaaaaaaaaa
OOOOOOOOOOOOOOOOOOOOOO�
(the 7 vowels, 22 times each).
