Humans have long sought healing, growth, regeneration, rejuvenation, and blessing from natural materials, whether at a healing spring in the Appalachian Mountains or from the dirt floor of a chapel in New Mexico. On the day of each new moon — believed by many to be a time of rebirth — visitors to Grace Clark’s In a New Light (Healing Dirt) in Like Magic are invited to enter the chapel-like room and apply charcoal earth to parts of their body in need of healing, harnessing the magic of belief in change.
