Spirits captured in stone

the long version

"This fascinating case study focuses on shamanism and the healing practices of the Taman, a formerly tribal society indigenous to the interior of Borneo. The Taman typically associate illness with an encounter with spirits that both seduce and torment a person in dreams or waking life. Rather than use medicines to counter the effect of these discomforting visitors, the shamans - called baliens - use stones that are said to contain the convergence of wild spirits that have come into being during the initiation ceremony"--Page 209.
