What is God? Length, breadth, height, and depth. ~ St Bernard of Clairvaux
These dimensions tend toward the idea of an invisible unity permeating the universe and ordering, or rather, allowing order to be created upon it. This god is impersonal and non-specific.
“So a Cistercian monk, eight times a day, for - on average - half an hour at a time, would sing communally in a bowl-vaulted chamber in precisely this way with the repeated notes and cadences of Georgia psalmody, with that being pretty much the only use he would make of his voice. No wonder the Cistercian movement had such power,”notes Malcolm Stewart in Sacred Geometry of the Star Diagram.
Stewart recounts the story of acoustician Dr. Alfrred Tomatis asked to visit a modernized monastery where the monks had become demoralized and unable to function. Observing that the monks were no longer required to sing the Divine Office together, he explained to the abbot that certain frequencies present in the human voice had an energizing influence on the brain. When the communal singing of the Divine Office resumed monastic life became livable again.
