As a medium, guide and son of the Casa, the entities gave Calvin permission to use the Crystal Bed (which has been energized & blessed by the entities) in his healing practice.  The Crystal Bed is used by the entities for cleansings and healings at the Casa. It prepares individuals to receive more assistance from the entities. In addition, it is an extension of the work of the entities to the people who cannot come to the Casa for treatment and healing   http://www.calvincates.com/crystal.html  954-200-5741
