Reddit mentions of The Essential Kabbalah: The Heart of Jewish Mysticism

Well, not too Orthodox, but ones I have on my ereader which I liked...

• Souls on Fire: Portraits and Legends of Hasidic Masters by Elie Wiesel. It's a really easy and engaging read. It doesn't go deep enough to get dry; which is either good or bad depending on what you're after. I worked at an old, historic building in the middle of nowhere. This was a great book to wander through in the woods.
  
  
• Tales of the Hasidim by Martin Buber. Buber goes deeper than Wiesel. It can be a little terse. Most of the book contains Hasidic stories presented in a few paragraphs. Buber was, first and foremost, a philosopher and scholar. He loved Hasidism and Judaism, but his approach was not Orthodox.
  
  
• Jewish Magic and Superstition: A Study in Folk Religion by Rabbi Joshua Trachtenberg. So, I adored this book. It explores (primarily) Jewish folklore around 1000 CE among the Rhineland Jews (Hasidei Ashkenaz). This community put forth work of the so called "Practical Kabbalah". The book examines Medieval Jewish beliefs in demons, angels, invocation magic, ghosts, amulets, and more. What I found interesting was that the approach was always very Jewish. In otherwords, they did not believe there existed a duality between the Devil with demons and God with angels. God remained supreme and One over all else in their superstitions. This book also traces some Jewish practices to their superstitious origins and contains many fascinating stories. It can be dry though. It's also available (legally) for free online!
  
  
• EVERYTHING BY DANIEL C. MATT. He's at the forefront of academic study of Jewish mysticism. He also translates beautifully. He's currently (and likely until the end of time) creating a new English translation of the Zohar. He has numerous short books containing brief translations of mystical Jewish texts. The Essential Kabbalah was short, sweet, pretty, and fun.
  
  
• The Jew in the Lotus by Rodger Kamenetz. In 1990 the first known meeting between a Jewish delegation and the Dalai Lama occurred. The delegation consisted of rabbis from different denominations with different views. They each present different aspects of Judaism. Kamenetz chronicles the historic event, but in a personal way. Through being a part of this endeavor, he learned about Buddhism and rekindled his connection to Judaism.
  
  
• The Golem and the Jinni: A Novel by Helene Wecker. BUY THIS BOOK. It's fiction (unlike the others). It's an immigrant story told using magical realism. A golem finds herself in the Jewish district of New York City in 1899. Meanwhile, a jinni is trapped in human form in the Syrian district. They are each new to the world in communities new to America. It's a beautiful book.
