I regularly attend ceremoies held by a guy who holds, i guess what you would call "westerrnised" ceremonies.
They are not religious, but i would say they have spiritual undertones.
Bascically he holds them on the weekends closest to the full/new moon,so every two weeks.
He "smudges" everyone before the ceremony with white sage.
We then all sit down and introduce ourselves and say why we are there.
This is followed by the first drink (syrian rue), which is then followd by 20mins of toning.(he has this wooden box thing which produces a note kinda like a harpsichord, which is tuned to the heart chakra, and we hum along to the tone)
After this, its time for the second drink (jurema tea)
Everyone then retretas to their respective matresses to embark on their journies.
Its held in a darkened room, but not pitch black, there are a few candles lit.
The music is mixed. He plays some recorded stuff. Mainly devotional mantras like Snatam Kuar, Oliver Shanti, Darpan. There is also some drumming music and healing sounds, icaros and various other stange stuff that is very apt for journeying.
There is also some live music, gongs, drums, rattles, digerdoos, chapaka, crystal singing bowls etc.
He will also burn insense during the ceremony palo santo, frankinsence, copal etc.
There is always at least one designated non drinker, who can help people out in times of trouble aswel as provide healing.
The doses are usually measured by shot glases. He rings a bell periodically to indicate an opportunity for another drink if you wish to go deeper, but this isnt set in stone, if you feel you need another drink then you just go up for one.
The ceremonies usually start around 7pm and go into the early hours of the morning.
Once everyone is back to earth, we have soup and a sharing, discussing our experiences and insights. This part is obviously optional, but most people always seem to share.
Im so greatful to have found a place where i can do this. I feel alot safer whence done in a ceremonial setting. Some of the states i have been in would have been quite difficult had i been on my own. Its comforting to be surrounded by others who are in the same boat as you.
Hope that has given you some good ideas.
