“Another common feature of many cultures is the use of what I call the “four D’s” to put people in contact with the wild wisdom of their true nature. The four D’s are drumming, dancing, drinking (or drugging), and dreaming. When the time comes for a sacred ceremony in a traditional society, the tribe’s mystics dress in formal outfits, then spend hours singing, chanting, telling stories, performing ancient dances, using psychoactive chemical compounds, and reporting on whatever visions come to them, awake or asleep.”
