Where you begin and end with your language says a lot. I appreciate your judicious use of words here.
(The more words I use to try describe it, the greater disservice is done to honour what actually lies there - all silent, all powerful).
The note you added above is also much appreciated, and worth repeating:
it's a VERY intensive experience, not to be taken lightly. make sure to put alot of prep into your intentions, and take the 1-2 weeks of preparatory measures seriously (specific diet, abstinence from alcohol, drugs, sex).
also make sure to meet whoever is leading the ceremony and make sure you are comfortable with them. ayahuasca has become something of a fad these past years and a lot of people are hosting without really knowing what they're doing or holding proper respect for the medicine.
I don't think I can watch that video right now, maybe I'll be in the mood to have a laugh~cry later though.
Your whole story was beautifully written, and was an inspiration to read.
I'm glad you shared it here.
