"dark" Ceremonial Magick Options

I am currently practicing traditional ceremonial magick, such as the

LBRP
MIddle Pillar
Circle of Light

etc......

However, i am noticing that several practitioners of the Left Hand Path who use simialir rituals but often inversed or reversed. Is the effect supposed to be the same and merely calling upon different forces of energy ... or are they designed for a different or even opposite purpose?

Greetings!
Thanks Kath for that segue...
Hybrid Theory, who was speaking of Satanists? Oh....you mean LHP! Two distinctly different ideas, both vegetables but there it ends...
Technically, all Satanists are, by inference, Christians,Jews or Muslim! (That should stir the pot!)
Why couldn't a Satanist use the QC or the Penta/hexagram rituals? Most of the folderol that is spewed by LaVey (and others) are merely Christian/Jewish rituals with the Gods names removed and demonic names replaced! And THAT isn't even remotely correct when considering Satanism.
Also...for those of you who think that dealing with Qlippothic energies is NOT a form of Kabbalah then guess again!
Who do you think theorized all of this dualistic miasma?
I reiterate my stand and Thanks for shopping at WalMart!

This is an editted version of my original response. I'm sometimes considered 'arrogant' when faced with various rebuttals and this is not what I wish to confer!
Why can't a Satanist use the QC or either the pentagram/hexagram rituals?
Especially in todays Newage communities...where, it appears, that Chaos Magic is all the rage.
Please make no mistake here... The LHP is not related to Satanism other than inference by one of the opposing political parties.
I am not fond of dualisms, feeling that they are too limiting and cast things in a terrible 'light'.
You may be correct in your assesment of Satanists though, since I do not believe in that hierarchy, cannot claim to know much about them...other than what has been foisted off on the general public about them.(From either side)
No, the use of the QC and the pentagram/hexagram ritual are lessons in energy manipulation. The pentagram ritual invoking or banishing the elemental forces and the hexagram ritual dealing with the planetary forces. Fairly neutral. You could, of course, use various god names/powers whilst using them but these needn't be Xtian (or whatever). The Aurum Solis are fond of using ancient Greek names and some have even tried to hermetically associate the Egyptian Neteru to their use.
The QC (Quabbalistic Cross) uses the energy flow of the universe to activate and/or modulate the energy flows of our spirtual bodies. Again neutral until you add various god names/powers to them.
This brings me to a possible hitch in the thinking about such rituals in the aspiring mage. Here you are already convinced that LHP means Satanism and then these rituals are associated, due to whatever book you were reading, to forces that are antithetical to Satanism. I think that with further reflection you may see otherwise, experience being a possible issue. If that sounded arrogant, I do apologize.
Note: I've left the original statement in for comedic purposes.
