I've read a few articles on tree association and which ones are good for wands or other thing. Most of them just gave me the idea that I should find a tree associated with what the purpose of the wand is and leave an offering. None of those however, told me what the offering should be, or how to ask for permission. Or what to do with the branch afterwards. So, can someone point me to a guide, or give an account of their own methods?
Any help appreciated, thanks in advance.
Basically, if you belonged to a tradition or a school that had rules, you wouldn't be asking. Therefore, it's all about how the wand feels to you in your individual practice. Think about what you're going to be using it for, what element(s) to which you feel it is properly aligned, and what your imagination shows you when you dream of 'wand.' Then try to match it.
Some trads hold the wand to be a symbol of air, others of fire. Most see it as male (since it's closer to phallic-shaped than cup-shaped...), many see it as similar to the athame in that it is often used for directing the energies, but it is more gentle and less forceful than the athame.
None of this need to bind you to the practice, however. Solitaries get to do it their way.
