Thank u very much Richful,

That was a sound explanation. Particularly the one abt beliefs. I am wondering if one could use sigil to alter one's belief system itself. As in if i want to shift my belief from objective to subjective reality,( as in completely ingrain the idea) can a sigil achieve that.
I am asking this because certain practices are restricted to certain things alone.eg. I'd read that a pentagram or cabbalah ritual only works for material things, as in even manifesting a job cannot be done using this pentagram ritual.
Are there limitations of that sorts for sigil.
I have no prejudices against channelling n metaphysical stuff as long as it is not a demon they r invoking. I've come across quite a few ppl in the forums discussing invoking demons.Now i dunno why someone wants to do that.
I guess as long as one doesn't affect the free will of others the practice of magic is fine.
