Well for Jewish mysticism its Spelled Kabbalah, the other spelling could get you another direction...I may be wrong, but if your not care full you will pull up stuff on Alister Crowley and his Qabalistic writings...
Look up these books for starters:
Kabbalah, A Very Short Introduction... By Joseph Dan
The Everything Kabbalah Book: Explore This Mystical Tradition--From Ancient Rituals to Modern Day Practices... By Mark Elber
Essential Kabbalah: The Heart of Jewish Mysticism... By Daniel C. Matt
Kabbalah For Dummies... By Arthur Kurzweil (the "For Dummies" books I find to really help)
