I've always given them to Father and my Guardian Demon, since I didn't know what else to do with them. After opening the chakras and working on feeling energy for a while, I've been able to form these more powerful than ever before, so I think I should also start using them myself. I just choose an adequate color, program them and direct them? I think I also saw around the groups something about amplifying their power by spinning them, vibrating runes into them etc.I figure it's like any energy work, but I'd just like some guidelines from more experienced people, just to make sure.
