That is a SPOT on assessment. I tend to believe in coincidence more than intent, but my experiences with ayahuasca and the timing makes it hard to feel the spirit of Gaia wasn't looking out for my ass. I contracted Lyme disease a year after my last ayahuasca journey and this makes ayahuasca feel like a tea party. If ayahuasca is "a little death" then Lyme disease is a perpetual dying experience. For two years I've been riding what feels like a brutal ayahuasca trip daily. Ayahuasca didn't in and of itself heal me. I continued a lot of self destructive behavior right up to my physical manifestations of illness. But as you said it's a tool. If not for ayahuasca I would not be able to feel my way through this mess. I would not know that there is another side. I would not know that the terror and misery were prime growth opportunity and that the "now" is just as important as that other side. Ayahuasca gave me a potential and planted it deep within for the right moment. Ayahuasca didn't fix my flaws but it told me that love was a choice I could choose at any moment and it would guide me to the light. Ayahuasca taught me what life was so I wouldn't have to be afraid when I faced it. Even my guide made a very strong point as we were leaving ceremony that the "hard work and healing is just beginning"
