Dr. Riley requires no introduction as a wise and experienced adviser, both of young and old, in the finer qualities of the mind and the attributes of the spirit. In this booklet will be found some of his sagest counsel for the guidance of every prayerful Christian who would attain mastery over self and the world. Dr. Riley deals with four imperatives which lead towards the heights of Christian living - victory over temper, the tongue, trouble and temptation - and indicates how this rich experience may become the possession of every earnest follower of the Lord.
