We still use some of the ancient Trappist sign language. The sign for God is the thumbs of both hands touching each other with the index fingers touching and pointing upward- forming a triangle for the Blessed Trinity.
The sign for bread is the same joining of the thumbs and fingers making this triangular shape but pointing outward and parallel to a table top- the shape of a wedge of fresh bread. We monks delight to notice the similarity. God is our Life, our true Bread, our Nourishment on the way.
