The mosque , which stood at he center of a complex, was the pivotal point around which all life revolved. People, receiving nourishment from such a center, became spiritually mature. Besides, they continued to be enriched intellectually and spiritually by utilizing the services offered by the school (madrasa), hospital and public kitchen. Eventually they would become a perfect human being who had balanced the material and spiritual aspects of life.
