In no branch of human knowledge has there been a more lively increase of the spirit of research during the past few years than in the study of Psychology, Concentration and Mental Discipline. The requests for authentic lessons in Thought Control, Mental Discipline and Concentration have never before been so great as in recent years. Students seeking knowledge in this field have advanced with the fuller possibilities provided by the constant addition of reliable teachings and more data for comparative study. Thousands of students of Concentration have received the reward of diligent, skillful and devoted study. Scholars in Psychology and Mental Discipline have specialized to so great an extent that many conclusions are less speculative than they were, while many more are thus available for arriving at a general judgment; and, in some directions at least, the time for drawing such conclusions, and so making practical use of such specialized research seems to have come, or to be close at hand. Many people, therefore, desire to have in an accessible form instruction that would throw a flood of light on these heretofore supposed esoteric studies that are of living and vital interest to the faith; and at the same time, "practical" questions by which is really denoted the application of "faith in one’s self" to life and to the needs of the day. It thus seems an appropriate time for the issue of a treatise, which shall aim at presenting a general study for the student of the present application of Concentration in various branches of the wide field which is included in the study of Psychology and Mental Habits, This volume is designed to supply such work, and seems to be well liked by men of known reputation as thinkers and scholars, teachers and divines, who are, one and all, firm upholders of the law of Concentration, Faith and Mental Discipline.
