Final madness?

This board doesn't seem active, but I'll post here anyway - something bothering me and it has bothered me at times in the past.

Is it possible to turn into a gibbering wreck with magick? Well of course I know it is - but just how gibbering, and how to avoid it?

My problem is this: i feel sometimes that a mere thought or prediction, charged with enough emotion, may be enough to produce a reaction. Now obviously i'd expect it to take a very powerful magician in order for a large outcome to be realised in this way, but since I don't believe in powerful magicians, only powerful emotions and inherently powerful technique (and experience) - and since this particular technique is both powerful and well-established, particularly in chaos magick - how can we prevent ourselves from say, thinking our parents will die and feeling the accompanying emotion of guilt, shame, fear, sadness - and thereby causing the effect to occur. Perhaps I'm being irrational, and maybe thinking this way implies i've already reached it, but I have heard of something called 'final madness'...

anyone know what this entails? I gather that it typically involves the debilitation of a fear of destroying oneself with mere thoughts and feelings. I can imagine that the only way to counter this so-called 'final' madness is to banish thoughts of self-destruction with laughter. So what then - we either become a madman laughing at himself every other minute when we have a morbid thought, or we become obsessively compulsive about performing counter-rituals?

I'm taking something to its extreme I suppose, and maybe I am talking mainly about highly experienced magicians - who have the second-nature ability to see every thought as ridiculous.

Hope this question gets some answers though - if there are people still following this group. If not, well I suppose I'll find an answer of my own sooner or later...
