The charging of the sigil is a two-part process that takes place while creating the sigil and then after with a specific charging and this is why it is important to be focused (ie. Not watching television or talking to your kids) while crafting your sigil.
We are just going to talk about the practical magick use for sigils. If you want to bring love in your life you would write what you want down and take some letters and make your sigil.
For example as follows:
Bring sweet love to me
You could take the first letter in each word (BSLTM) and overlap them or connect them in an artful fashion. You can create pictures with letters in it. The goal is to create something that requires a little extra effort and at first, it can be a bit difficult if you aren’t used to it. There is no right or wrong in this kind of sigil creation as it is your own desire and manifestation of what you want. This is a creative process and while you are creating your own sigil you are putting power and energy into your desired end result.
When you create your sigil you want to make the sentence fairly short but direct. Sigil work is usually done with spell work and it is not the sigils job to be super-specific - you will create a request for timeframes and what you are looking for in other ways. Think of the sigil as an overall plea to the universe that you are putting your own time and energy into.
During the sigil creation process, you must focus energy into your sigil. Picking the time is important and it is good to do this during a full or waxing moon. You will want to charge it with energy on a positive energy day but beyond that… the exact time and day can be up to you.
Some examples are charging it during a full moon or chanting. You use a prayer or tell it what to do. The goal is to place further energy and direction into the sigil once it is created. The more tools you can bring together to charge the sigil the better and more prolific the sigil can be. When you are done with your sigil you will spend time focusing on what you want until you feel that the sigil is complete.
