The Book of the Sacred Magic of Abramelin the Mage is a 15th-century grimoire describing how an individual retire for six months and encounter the Holy Guardian Angel. Although the instructions may seem quite simple, few have managed to complete this operation. In 1977 the author attempted to adapt the ritual to twentieth century conditions, and his diary is now published by Aeon Books as The Abramelin Diaries.

While the Abramelin Diaries was being edited and published, tthe author made a number of short YouTube videos about his experiences. These created so much interest, that the author has edited the transcriptsto create Thoughts on Abramelin.
