"Hair is powerful to the Algonquin," according to Evan T. Pritchard who has written extensively about the traditions of these Native American people. "It collects the vibrations of the energies around you and is important to purify carefully. Hair also holds the smell of the smoke a long time. This is part of why native people don't cut their hair."
In the sacred dances of Sufi dervishes in Kurdistan, worshippers enter into a trance state tossing their long hair back and forth over their heads. Thich Nhat Hanh, a Zen master, challenges us to see the hairs on our heads as "ambassadors of truth"; he counsels us to observe them well to discover the messages each hair is sending us.
