My Understanding : Steady intellect: When wisdom directs itself toward the senses and conscience, it manifests openly in the world. However, when it works on the intellect, conscience, and senses, it illuminates internally but does not necessarily show outwardly. This form of wisdom shines like a ray of light reflecting from a mirror. The senses and conscience carry this wisdom within. This stage of inner clarity and harmony is called peace.
