The fourth weekly installment of Jay Michaelson‘s introductory series to kabbalah at Huffingtonpost has been posted a few days ago. It’s subtitle is a bit misleading: “Spiritual practice”. It is not entirely correct as he goes on discussing theosophical, prophetic (aka ecstatic) and practical (magical) kabbalah. These are indeed various types of practices of kabbalah, but to the extent they are spiritual is debatable. Otherwise the piece is excellent.
