The effort should be to find inward stillness through a loving search within the heart's depths for what may be called "the soul," what I have called "the Overself." This is not the soul thought of by a judge when he passes the sentence of death and asks the Lord to have mercy on the condemned man's soul. It is the Holy Ghost of Christian faith, the diviner part of man which dwells in eternity. The nearer we get to it in our striving, the greater will be the mental peace we shall feel. It can be found and felt even whilst thoughts continue to move through the mind, although they will necessarily be thoughts of a most elevated nature for the baser ones could not obtain entry during this mood.
