The "occult", and "cult" are not necessarily related.
The use of magic (sorry T.I., but my linguistic searches reveal that the word "magick" is a corruption to make it look older) is in and of itself not a good or a bad thing.
It is the motivation behind it. Even in anger, you must still summon love to perform these rites (which are basically a physical affirmation/reinforcement of a postulate anyway). If you go home from an argument wishing that your opponent would fall out of the evolutionary tree and break a few limbs, that's gonna come back and smack you in the face so hard your ears will be ringing for weeks.
You must take the time to cool down, and then look at the situation objectively. Perhaps you're the one pushing diarrhea uphill with a fork, and need to apologise to the other party? If you're 100% certain of your facts, then put it out there: "Power/Life Force/God/I Am/Other Name for Supreme Being of Universe, thank you for showing BOTH OF US the error of our ways so that we may find peace and correctness on this issue?"
When you look at so many HCOBs, lrh was venting his spleen over some perceived insult or threat--LOVE was not the motivation behind those bulletins. By all means, he should have typed it up, and then shredded it to get it out of his own universe, and then look for a more "alleged Scientological ARC" solution.
Edit:
I was only ever taught one particular "ritual" which was supposed to bring in money. It didn't. But I have used it and variations of it as a physical activity that reinforces the postulate I am creating. The much malighned Bible has it right when it says "Ask as though you have received." If you keep asking for it tomorrow, well tomorrow never comes. You ask for it as though it's already sitting on the dining room table. In some circumstances where I have perceived the need for some sort of ritual, not to re-inforce my belief but to bring about belief in a being that would otherwise do harm, I have made up rituals on the spot. "Give me a glass of water, some salt and, and, and ... a turkey baster!"
So I reiterate: Magic/Occult is neither black nor white. It is the practitioner who imbues good or evil on the powers that are there for us all.
