I have a question about a meditation item, There have been similar discussions here.  I have been dedicated for years now btw.  
I enjoy martial arts and use them for exercise, spiritual confidence, and mental clarity,  I absolutely love practicing with the short staff (Jo staff / quarter staff in some quarters)
I want to engrave or dremel tool a sigil and/or runes into one to make it feel more mine.  Do I put Father Satan's  and a power rune, or use runes as and alphabet to spell something?
Look I know this is stupid and silly overall, but I would enjoy the significance.  Hail to all my friends, and especially the one that is most high.  The Father.
