I'm fairly new to the world of magick, and before I cast my first spell, I have a few questions. I have done a fair bit of research, but it still leaves me with a few questions that I need clarified.

1. How do you raise, direct and release energy? Is this done before, after, or during a spell?
2. I have read somewhere that orgasming is a form of raising energy, but can this only be done when using spells for sexual purposes?
3. What exactly is divine blessings? and do should they be invoked before casting a spell?
