"After my death a book will be found, which I commenced to write at the time when I was beginning to put in practice this Art, which, reckoning the number of the years, was in 1409, until to-day on which I am arrived at the 96th32 year of mine age, with all honour and augmentation of fortune; and in this book can be read in detail even to the very least thing which I have done. But here, as I have aforesaid, I will describe only the most remarkable."- The Sacred Magic of Abramelin the Mage - Book 1, Chapter 8.
I keep journals and have done since starting my magical work, as probably most magicians do, they are a permanent record of the work I do, and the results I get. I try to write most things in them, but if I had to write everything down that I did, and the results I got, I would never get time to do anything else, so I have to be selective and just write down the main things.
I am now starting to work on my next book, a follow up volume to the Ritual Chaos Magic Workbook, which will include more about my experiences and the results I have got (including some hair raising tales about dealing with demons, and Thanatos following me and popping up on MSN)!
