In the late 1980s I undertook a Working based closely on Liber V vel Reguli, working daily for about a year or so, and found it very interesting.
There were certain things that I didn't stick to - I rarely use robes or weapons, and I didn't mark the position of Boleskine when passing that point of the circle, though on the other hand I did retain the spiral dances - but I found it to have powerful effects on consciousness/awareness.
During the last few weeks of practise, I found that violence was following me around, manifesting in people around me though never touching me personally. Towards the end of this period, one evening I was walking across the road, and heard a muffled explosion. I remember thinking at the time "Ah, the IRA bombing campaign has started early this year", then saw that a car in front of me had burst into flames from under its engine bonnet. At the same time, there was a sudden and strong sensation in my solar plexus, and I knew with absolute certainty that this event was connected with my daily working.
So, exploding cars and surrounding violence apart, this is a very interesting Working to undertake and one that I can recommend.
