I have spent the past 29 days on a STRICT Ayahuasca spiritual diet. If all goes well (the universe seems to have been postponing things), I should have a fascinating writeup to share with everyone in a day or two. Never before have I attempted something like this.
No salt, no spice, and no oil are supposed to straighten one's energy body, so the spirits can heal more easily, like the body becomes a still pond of water. During my experiment (during most of which I was temporarily homeless, hence the lack of Aya ceremonies), Changa seemed to hit me 3x as hard, and mushrooms transformed my visual processing in a way never experienced before--focus became impossible, peripherals expanded, everything became like a watercolor, and, yes, the trees talked.
There are a lot of spiritual traditions that have interesting overlaps as far as diet and sensitivity is concerned.
If you want to explore going VERY DEEP, the dieta element will take you further.
However, a relatively clean diet (eat fresh whole foods the day of, and leave a few hours of digestion before drinking) will be perfectly fine. It normally takes a lot of willpower for me to stick to a restrictive diet and I didn't always do it, to no ill effect.
I can't say it enough... eat for your elves! Just respect the amazing creation that you are... treating yourself with love and respect goes a long way.

Don't get hammered and eat 19 bags of Cheetos right before drinking... that's not good for the elves, anyway, if you know what I mean.
Pork seems to give some people horrifying visions. That's just the word on the street. :shock:
