Do what thou wilt shall be the whole of the law.

I've seen that after performing Liber XLIV I experience the exact thing Froclown mentioned, a fresh charge of spiritual energy. I'm much better at being in the moment afterward, and have more AHA moments, and generally feel better and see, even more so than usual, the beauty in the world around me. I figured Liber V would have a greater effect to that end.
