My favorite was giving a group of 20 people each a sheet of paper, and a different colour marker. Then having them write a paragraph of intentions for the trip, intentions for the group, intentions for the month, year, and long term goals.
Then we cut these all up and placed in a glass bowl of water,
Let them all mix (looked super cool and rainbow colorful!) there was a string we each tied a knot in doing "knot magic" criss crossing atop the bowl, on top of which a candle was placed and lit.
Then we each had a shot glass with LSD and MDMA in it, which we took turns walking up to the candle, letting the flame lick the bottom of the glass, and down the hatch.
Later we used the candle flame and hemp wick to smoke DMT.
Beautiful ceremony.
Sex magick pursued.
I try to invent the ritual on the fly with whats available, eclectically taking aspects of each individuals beliefs and integrating them into the ceremony.
I once participated in an LSD ritual with over 100 people, all praying and dosing at the same time.
As for coke and heroin, I just try to cleanse it of the blood money, before partaking.
I like to make sigils with crystal ketamine and snort them.
During DMT extraction sometimes I mix my blood and state a goal of what sort of life I would like to be living, what I'm trying to manifest, at different stages, sometimes during recrystalization giving it a nice red hue - and smoke it. Opens a portal, kind of like bungee jumping from point A to point B without knowing how you got there. Dangerous, my ass still hurts, but I did have a shit ton of fun. Maybe should be more careful about getting into a meditative state of gnosis to ensure there are no renegade thoughts/fears involved...
