Marisa Meltzer has a multi-faceted, fascinating piece on ayahuasca:
There are two main ways of taking ayahuasca: with a shaman or as part of a religious service. In a shamanic ceremony, you sit on a mat and go within, not interacting with anyone else. The religious use is far different. The Santo Daime ("holy give me" in Portuguese) sect, which combines Christianity with Kardecist Spiritism, believes that the tea is a sacrament, a manifestation of Jesus Christ that brings practitioners closer to God. A Santo Daime service lasts four or five hours, sometimes as long as 14. Men and women sit on opposite sides of the room, and there are candles and a table in the center of the room like an altar.
Meltzer retells her own vision quest guided by a shaman in a Manhattan yoga studio:
I saw vignettes from my childhood, almost like watching a movie about my relationship with my parents. At first, each episode highlighted my strength and perseverance during an unhappy childhood. I could feel the drug congratulating me for surviving and thriving. And then, as if I were in A Christmas Carol, I was taken through more views of my childhood, this time illustrating ways in which I was hard on my family. I had a newfound sympathy for my parents. I opened my eyes and stared at the moon through a large skylight in the ceiling of the yoga studio and felt myself crying. But the rapid-fire insights didn’t feel violent or overwhelming; instead, they were gentle and healing, as if these answers had always been within me.
