if you so hardly believe in magic or are interested , id think twice.

not just from this link either.

if you believe in something , you should with your heart.
one of the key aspects of magic is too believe , just as god , or what have you.
if you have doubts then , you are unsure , and the art would have a useless meaning.

but if you consider or agree with this then , you would have too consider the other , myths or perceptions of what is.
like karma for instance.

also ,
if you believe that you can summon angels.
you are not christian
though i could care less if you are , i am not.
i respect those beliefs though.
