My power objects are wrapped in or sit on a colorful woven fabric called a mesa cloth with regular, geometric patterns. Usually, there is a column looking like a zigzag of lightning running down the length of the middle of the cloth. This column mediates between the two sides of the mesa and represents the inherent duality of life: the bottom represents hucha, or the "heavy" energies (...); the upper part represents sami, or "light" energies. (...) they represent a complementarity between the "Underworld" and the "Upperworld" or from a western psychological standpoint, between the shadow and the ideal, or the subconscious and conscious, which are in a dynamic dance in the psyche. The column in the middle represents the balancing of these two polarities as they are expressed in physical action here in the middle world."
