Day 05 of 07 is about Mental Concentration as it relates to Mastery Over The Power Of Thought. Thought is Power. We do nothing of note – whether establishing organizations to initiating revolutionary social change to building great monuments to launching human beings into space – without first forging such concepts in mind through the Power of Thought. Those who get things done along significant lines of accomplishment differ from those who do not in that they neither allow their dominant aim to be diluted by conflicting thoughts, nor let go the vice-like grip of attention to their dominant Idea, lest it fade from memory. One can live a life of significance through this ability to think with absolute clarity; to think with resolute discipline; to entertain only what matters in mind. This lesson sets the stage!
