Windhorse, or hiimori in Mongolian, refers to personal spiritual power. When I spent 4 years at Martin Prechtel’s school of spiritual ecology in New Mexico, he often referenced Mongolian culture, language and music in his teaching. So books about Mongolian Shamanism found their way onto my bookshelf. And in Chosen by the Spirits, by Sarangerel, I met the concept of windhorse.
Now many years later a drum has appeared whose image goes by this name.
