Just remember not to believe everything, there are some history that are far from the truth. As for belief, belief is the main source in magick. Without it, a spell would be emotionless, and thoughtless.
As you did mention meditation, some meditation is used for enlightenment, some people can spend about 5 hours or more meditating. If you want to learn more about magick, then I suggest reading through some of the articles and some of the forums, also going through some reliable sites (which are hard to find).
You are far from being ignorance, just me we have seen ignorance.
