I found this in a story on Elephant Journal about how Ayahuasca helped the author overcome depression and addiction:
In many of my ceremonies, I was brought back to feelings and memories I had walled off, and the medicine held me there while I cried uncontrollably; my whole body shaking in terror while I was vomiting and sweating. I hated every second of it—but then came the compassion.
I don’t know if this compassion came from “God” or ayahuasca or my higher soul-self. It doesn’t really matter. What matters is that integration happened by feeling it all, releasing the pain, and being held in love and kindness afterward.
It rung a chord in me because I myself went through a long period of being detached from my feelings, and the whole idea of coming through past trauma’s in order to re-integrate sounds very familiar, although for me this came through many meditative experiences on the edge of sleep.
I think that very few people come through childhood without a measure of trauma, although of course some people experience very much more severe events than others. Anyway I thought this was a really interesting article on the topic of integration in general.
