Every Tradition Mage is familiar with the Nine Spheres of Magick. Each Tradition (Hell, each Mage) has their own perceptions on the nature of these Spheres. What I offer here is a basic explanation of my perceptions of each Sphere. By focusing your ojas (Life Energies) on the name of each Sphere (except Entropy because I still haven't figured that one out) you may be able to gain a greater understanding of my perceptions of the magick involved with that Sphere. You might even learn something you didn't know before.
Correspondence: Some call it the manipulation of Space I say "Space" is a misguided answer to a misunderstood question. My theories on this Sphere use a different understanding of the question to gain a different answer.
Entropy: I've heard that Entropy has to do with averything from Luck to Decay. When I figure some it out I'll get it on here but if you want details in the mean time, you'd be better off talking to a Euthanatos, it's their art.
Forces: Namely the forces of nature. However they are manifested a mage can use them as weapons or valuable tools to accomplish difficult or seemingly impossible acts.
Life: All living things Have a life essence. You can learn a lot about someone by their Life essence. Life Magicks also work in other, more medical, ways. I'll let you know how to use that way as soon as I figure out how.
Matter: Any physical substance that's not "alive" qualifies as matter. This Sphere deals in working with matter much like clay worker with a pottery wheel works his lump of clay into a beautiful clay pot.
Mind: Me, Myself, and I have voted this, my favorite Sphere. This Sphere covers aspects of the Mind and it's ability to affect and influence other minds kinda like Mental Powers.
Prime: is the raw stuff of reality, sort of along the same lines as Quintessence, I think. One really big use of this Sphere is the ability to recharge your Avatar beyond it's natural levels, comes in handy when you're having a bad day.
Spirit: This Sphere was first runner up on my favorites list. There's a whole other side to being alive that most people just don't realize, The Spiritual side. This Sphere deals with Spirits and the Spirit World (a.k.a. The Umbra).
Time: This Sphere involves "Time" in much the same way the Sphere of Correspondence involves "Space". Like the Late Great Janis Joplin once said "Tomorrow never happens. It's all just the same fucking day, man." I couldn't have said it better myself.
