“As the energy of light leaves its traces upon photographic emulsion and as the energy of sound leaves its traces upon recording tape, so also does the energy of human intention leave its traces upon physical space. Part of the power of a place is thus created by the power of human intention. And that power is permanent. It saturates and surrounds the holy places. It reaches out across the centuries, evoking in the hearts of pilgrims visiting today, the same love and exaltation that inspired the original builders of the shrines.”

--- Martin Gray, Sacred Earth 2009
