A sigil is a magickal symbol used to help one with wha they wish. (Money, love, fame, protection and much more) It is made by first typing out a sentence in all caps usually beginning with I wish, I want, or my wish is, so on and so forth like so:
I WISH TO BE PROTECTED
Then, you would proceed to take out any double letters as such:
I WSH TO BE PRCD
You would then begin to make a symbol using the letters. You can also if you wish take out letters that look similiar. (Such as W and M, H and I, ect.) Typically one uses a circle or triangle around their sigil, but it is not always required to do so.
Also, after one is complete they usually discard of the sigil in some way and try to forget about it. This is believed to make the sigil take effect. However, some believe that you don't need to discard of it at all. This, I believe is based on personal beliefs and either way is fine.
I will put a step to step illustration of the sigil making process into my photos on a step by step illustrations. Feel free to check them out. If you have any questions my mail is open.
