I have struggled with the same issue myself. When I was five I had a vision that sparked my interest in mystecism. Later in life, while exploring various spiritual systems, I found practical magick and found that I had a talent for it. I see no reason for viewing them as separate things. Almost all great spiritual leaders performed actions that effected the world around them. Some of these actions were accomplished through magick, or supernatural means.
I see practical magick as both a means for dealing with life to the point that we can focus our mind on spiritual illumination. Maslows pyramid teaches us that its hard to work on self actualization while our basic needs are in dissarray after all. Thaumaturgy is also the rays of light that reflect our illumination into the world. I have no interest in spiritual persuits that are divorced from the manifest world.
While there is no inherent contradiction between Illumination and Sorcery, there is still the matter of striking a balance. I happen to know that our good Frater has been reading up on a bit of the Hoodoo of late, which while not devoid of spirit, is practiced more by people who rely on faith rather than a quest for gnosis as the cornerstone of their spiritual lives. Nothing wrong with that, but its not Frater BH's path, nor is it mine.
I strongly suspect that his post is the result of a gentle nudging from his HGA to not stray to far from the path. I recognize this because I get those nudges all the time. I used to get them even when I would get caught up in Buddhist Lower Activity practices rather than the Pure search for enlightenment.
Recently I have made some firm decisions about my activties as a Sorcerer vs those of a Mystic. I have some things I need to accomplish over the next few years and than I will retire from practical magick and devote myself fully to BEING. (ie: Gnosis is not enough. You must BE). These decisions have eased the burden of balance lately, but I have had trouble in the past keeping that balance, and so I sympathize.
I only wish to point out to my freind, that he claims that he is : "a man without religion seeking the ultimate god, the ultimate unity." If this is ALL he is interested in or called to, than he is going about it in one of the worst possible ways. GD, Enochian, Hoodoo, etc aint gonna get you there in the fastest most efficient manner. You are in fact never very far from what you seek and if thats really all you are looking for than drop everything labeled "magick" which takes long and meandering routes back and forth along the paths, assidulously mapping them as you go, and take on something more direct like Zen, Dzogchen, or some other type of meditation. It will shoot you straight up the middle pillar.
But I suspect that you are actually called to more than just seeking the ultimate God, the ultimate unity. I suspect that you are called to magick, and at least for a time, must do the balancing act between Sorcery and Illumination.
Of course. I could be wrong. I talk out of my ass a lot.
