Magic Forums

I've been reading the forums a lot now and have a small grasp on magick and what Wicca is, but I have been trying to create a psi ball as a start to my magick practice. Well "trying" is the keyword here because I haven't been able to make one, or at least feel the energy from it. I also read somewhere that the magick we do here is in the spiritual world and physical in ways, as certain things you can do because it's spiritual, but other things you can't do because it is too physical for it to happen. I haven't really tried spells yet either, but I haven't been able to meditate correctly, or at least I think. Can anybody help me on what I'm having trouble with? As I am new and I hope this community help me. Thank you.
