Here is a quote from
Peter J. Carroll’s „Liber Null & Psychonaut“ from the chapter „Gnosis“:
Emotive arousal of any sort can theoretically be used, even love or grief in extreme circumstances, but in practice only anger, fear, and horror can easily be generated in sufficient strengths to achieve the requisite effect. The wellknown ability of fear and anger to paralyze the mind indicates their effectiveness, yet the magician must never lose sight of the objectives of his working.
The main difficulty I see is in generating intense feelings in the abstract, i.e. without thinking about someone or something that triggered those feelings which may be easier with some emotions than with others. Carroll may be right when he specifically singles out anger or fear because many people carry a kind of diffuse anger in them all the time; for others a certain groundswell of vague anxiety is practically a part of their personality. Other people may require something to be ashamed about or afraid of, for example, and it’s probably not easy to conjure up such an emotion without constantly thinking about its source.
I personally tend to avoid the energy metaphor because it invariably evokes a basically neutral force like electricity. Electrical energy can be used to power your toaster, TV, computer, for all kinds of appliances, and it doesn’t matter how it’s been generated, whether from burning coal or oil, a pile of uranium pellets, solar panels and so on. This would be a prime example for how that metaphor (and its involuntary association with electricity) is misleading – intense hate, for example, can be considered ‚energy‘ in general but is it suitable for success rituals, for example? Hate ‚energy‘, again unlike neutral electricity, has a certain tinge to it that may spoil a ritual performed for more benign results.
Anyway, the use of intense feelings as a driving magical force is mostly a chaos magic method where they are used as ‚propellants‘ for sigils. Most other magical rituals (and correct me if I’m wrong) seem to require calm solemnity and focus or the arousal of subtler and more stable emotions like quasi-religious awe; reciting a psalm and then suddenly going berserk with anger seems like a jarring inconsistency. However, I cannot speak for the LHP, it’s adherents are probably more able to integrate sustained ‚negative‘ emotions into their rituals. But whether LHP or RHP, it’s the ritual itself that engenders feelings in 'classic' magic, not the operator‘ specific emotional makeup and its expression.
It’s also a question whether you are able to control these emotional forces sufficiently, arouse them at will and then put them back into the box again, so to speak. That’s perhaps the only instance where emotionally repressed persons have a certain advantage exactly because they have this (excessive) iron control - but then they might have difficulties to pry those intense feelings out of the box in the first place.
So yes, anger can be definitely used to charge chaos sigils – if you can handle it. I’m not so sure about shame or despair though, they seem to be more self-destructive and directed inwards but it really depends on what kind of person you are, I guess.
