In all spiritual science there is a fundamental principle which cannot be transgressed without sacrificing success. It runs as follows: All knowledge pursued merely for the enrichment of personal learning and the accumulation of personal treasure leads you away from the path; but all knowledge pursued for growth to ripeness within the process of human ennoblement and cosmic development brings you a step forward. This law must be strictly observed, and no student is genuine until he has adopted it as a guide for his whole life. This truth can be expressed in the following short sentence: Every idea which does not become your ideal slays a force in your soul; every idea which becomes your ideal creates within you life-forces.
