The circle and triangle are such basic shapes, they go back a long way in history and have been used by many peoples to symbolize a wide variety of concepts - many of them we Humanists would not agree with. However, the meaning of the triangle here is prosperity or, as the Hittites used it: well, good, and healthy. This references to the focus of the Contemplatives on personal development. The circle is broken into two sections, top and bottom. The top section stands for the faculty of reason and the bottom section for spirituality.
