Simply stated, this is the diary of the encounters with an angel. Joseph Caro was one of the rare individuals who merited to be instructed by a Maggid – a private angelic teacher – who revealed to him many kabbalistic teachings. The Maggid exhorted Caro to sanctify and purify himself, and he revealed to him events that would take place in the future. The teachings of the Maggid are translated in English for the first time, so that now everybody can benefit from them in order to purify and perfect his bonding with the Creator.
