hey brother, welcome!
your plan sounds noble. i would stay away from meat on your dieta. the true work that takes place in the jungle involves a strict vegitarian regimen and would say that you wana do that as far out from your ceremony as possible.
cleanse, cleanse, cleanse! you can't be reverent enough with this medicine. here's how it was when i worked with the Seicoya of the Ecuadorian Amazon:
1. vegetarian, simple dieta of rice, beans, vegetables. lite meals and only 3 a day. it feels like fasting to be honest because the calories are so minimal. i'm a vegan and even i was feeling 'cleaner' with such a small amount of food. try to do this for a week if you have the discipline.
2. no sex/masturbation/ejaculating for, at the very least, a couple days before your ceremony. i'll go for weeks.
3. no alcohol or drugs....even the righteous plant medicines (ganja, mushrooms, cactus, etc.) for a week before.
4. cleaning of the psyche/emotions through meditation/stillness/alone time. as important as cleaning your physical body!
the day of your ceremony, clean your space. burn sage. light candles. take a shower and don't put on any deoderants/perfumes/etc. be clean and clear. wear white if you can. turn off all electronic stuff in your house if you can. no cell phones, alarms, pagers, t.v., etc.
have a righteous journey brother. i have worked with the vine a great deal and i owe my life to it without question. this is the medicine that can heal the world through you. keep that in mind as your work begins. you are doing this for the world even if you think it's just for you. the growth and evolution of one is the growth and evolution of all.
with the deepest love and gratitude!
