Regarding my own performance:
I'm still observing various subjective and objective effects attributable to the performance, including indirect "ripple effects" that I've only been able to trace to it after the fact (and which always have to be scrutinized over time to avoid attributing anything and everything to the ritual). Given that it has only been 9 days (keeping to the numerology of 9: "9 months between performances" and "9 days between posts" here), I imagine that there will be additional effects. When I say, "effects," I mean anything noteworthy within my UPG or in the outside world that seems to connect somehow to my UPG relative to the ritual.
The actual experience of the ritual was nothing unexpected. I approached it through the frame rite (as I mentioned in the original posts in this thread) and took my time with it. I copied out the sigil by hand, dressed it with oils, smoked it with incense, and then cast it within the frame immediately before the actual performance of the Headless Rite. The rest went as planned. I was in Dublin at the time of performance and then went to a public graveyard to meditate, which was nice, but nothing went bump in the night. I did have a very heightened "buzzing" sensation moving around my body until the next morning.
There have been some initiatory developments involving an unexpected invitation from a magical-religious group in the USA that I had only been peripherally aware of and a very powerful "kundalini" experience during meditation that connected with some of the imagery that arose previously during the performance of the rite. At this point, I am keeping an open mind given that the feeling of this rite has been very different from how it felt when I performed it in Paris over 9 months ago. I am very interested in the reports and experiences of others, wondering how they might connect to my own via the sigil (if it has worked as intended).
