Shamanism is the oldest recorded spiritual practise found in cultures all over the world, including my own (Chinese Taiwanese). Through entering into a non-rational mind space via a number of tools such as altered breath, ecstatic dance, chanting, rattling and drumming, and the consumption of specific plants (in my case, non-entheogenic plants), the practitioner can tap into a reality (and set of brainwaves) that is broader than the mundane and access the Unseen and the Otherwordly to receive beneficial messages and then deliver them to those asking for help.
