The Grade of Exempt Adept, associated with Chesed, is perfected when the power of the sphere of Mars, Geburah, has been drawn along the 19th path back to Chesed. In doing this one places oneself in Chesed, for the knowledge of the Great Arcanum, of the Secret of all spiritual activities, is not open to him who has risen no higher than the Grade of Major Adept. That is to say, the 19th Path is not open so long as we are no further along the Way of Return than Geburah, and the power from Geburah must be brought over from the side of Severity on the Tree of Life to the side of Mercy, by a process initiated from the point-of-view afforded by Chesed.
When all the desires of the seeker for light have been unified in the one desire to be a free, unobstructed vehicle for the manifestation of the cyclic activities of the cosmos, he has traversed the first path leading to the Grade of Exempt Adept, the path of the letter Kaph, corresponding to the Wheel of Fortune in the Tarot. After this, by a supreme effort of imagination, he sees behind the mechanistic expression of the Life-Power in the cosmic cycles the operation of a Living Will, and through the 19th Path he transmutes the activities of the serpent-power, and this transmutation is pictured in the Tarot by the woman taming the lion.
You will remember that lion (in Hebrew), the name of the zodiacal sign Leo, is the number 216, and that this is the number of Geburah, one of the names of the sphere of Mars. Note, too, that 216 is 9 by reduction, and 9 is the number of Teth, the letter corresponding to the 19th Path. 216 is also the number of [the Hebrew word for] Sight, the function assigned to the 15th path, and of wrath or excitement, which is the function of the 25th path, that of Probation or Trial. The path to which Sight is attributed is that of Aries, ruled by Mars. And the path to which excitement is attributed is that of Sagittarius. It thus becomes evident that all these [Hebrew] words – strength, the lion, Sight, and excitement, are related to the fiery power which we have learned to associate with the Mars-vibration.
This vibration, you will recall, is especially active in self-consciousness, and the feeling of strength which it gives is misinterpreted by people who have not progressed beyond self-consciousness. The misinterpretation arises from the illusion of separateness, which engenders the feeling of ‘myness’, and this feeling is the root of belief in personal will. This is why the Sephirah Geburah is said to represent personal will, which is merely the misunderstanding of the power of undeviating cosmic law in its manifestation through personal centers of expression.
The Major Adept still feels the illusion, although he has overcome the delusion caused by it. But the Exempt Adept, having in his union with the One Self so identified himself with the cosmic memory that he never forgets his relation to the Sources of All, is almost wholly liberated from even the illusion. Almost, I say, because there are times when even he who perfectly remembers the Self (Chesed is the Sephirah of Memory) must identify himself with the relative states of being in order to serve, in order to perform the actions necessary to his part in the Great Work. And at such times he feels the illusion of separateness as much as anybody else.
