Sigil magick is a form of magick that you use spiritual symbols or alphabets to gain your goal through your craft. Either it's just fortune, money, love or even summoning entities as some people do. I am going to be giving you a simple way to use sigils at your will.
1. Find a quiet good place you think is good to perform a spell. You may have an altar or just this private spot in your house or bedroom.
2. Grab a paper and pen. (optional: candles and incense)
3. Get into a meditative state to raise your vibrations.
4. Write down a simple short sentence which points out your goal. I'll be using an example: "I want to have good grades"
5. Now take point out every letter from the first one to the last one but if you encounter a letter which appears twice scrap it. Example(using the sentence in point 4): "IWANTOHVEGRS"
6. Now that you got that whole scramble of different letters, write them down in a magickal alphabet such as theban, runic ect.
7. Ones your finished you can either put the sigil you wrote in your magickal alphabet on a paper and carry that paper around, place it somewhere in your house or burn it.
The point of using sigil magick is to forget what you asked for easier. Remember how I posted in one of my previous spell post that you should completely forget about your spell? This helps with just that. While you will not easily remember it, your spirit/higher self will and it will manifest it for you.
If you decide not to burn or throw away your sigil, you can make it's effect more powerful by constantly powering it. Either by using crystals, rituals, a circle spell, visualization and anything that is comfortable to you.
Example of a summoning circle.
