"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?

That is not entirely true. Reversal of energy doesn't necessarily land you in the same place. Alot of 'LHP' magic is labeled that because some of it utilizes sex in its workings. People mistakenly think that LHP is one that raises materialism above spiritualism. You could argue that practising Goetic Magic as being LHP as it consorts with demons. The definitions of RHP and LHP is a fuzzy one, oftimes refered to in the third person as being diametrically opposed to the path you are on. You need to research the differences abit more. One can practice the ritual QC, penta/hexagram rituals and still be LHP. It's never as cut and dried as some propose. Good luck!

Actually Bym, I disagree with you here. That's like saying a ceremonial magickian can revert the rituals of the pentragrams and hexagrams and replace the archangels with demons and still be on God's side. That would be like betraying God.
Also, Satanists are known to be very prideful people; most of them would actually die for their beliefs. So it is illogical to think that a Satanist would pratice those rituals you stated but yet would still consider himself a Satanist. He just wouldn't do that cuz he he has too much pride and adores Satan too much. Even if he did do it, it would actually take away from his life and idealogies as a Satanist and NOT add onto them ( some would think this, given how your experimenting). This is wrong.
