Will and Desire lie at the doors of Meditation and Concentration. If we desire truth with the same intensity that we had formerly wished for success, money, or gratification, we will speedily acquire meditation and possess concentration. If we do all our acts, small and great, every moment, for the sake of the whole human race, as representing the Supreme Self, then every cell and fibre of the body and inner man will be turned in one direction, resulting in perfect concentration. This is expressed in the New Testament in the statement that if the eye is single the whole body will be full of light, and in the Bhagavad Gita it is still more clearly and comprehensively given through the different chapters. In one it is beautifully put as the lighting up in us of the Supreme One, who then becomes visible. Let us meditate on that which is in us as the Highest Self, concentrate upon it, and will to work for it as dwelling in every human heart.
— William Q. Judge, from “Meditation, Concentration, Will”
