You [God] are a fire that takes away the coldness, illuminates the mind with its light, and causes me to know your truth and I know that you are beauty and wisdom itself. The food of angels, you give yourself to man in this fire of your love
St. Catherine of SienaThe city is the image of the soul, the surrounding walls being the frontier between the outward and inward life. The gates are the faculties or senses connecting the life of the soul with the outward world. Living springs of water rise within it. And in the centre, where beats the heart, stands the holy sanctuary.
