"I am the birthless, the deathless, the blissful, the omniscient, the omnipotent, ever-glorious Soul." Think on it day and night; think on it till it becomes part and parcel of your life. Meditate upon it, and out of that will come work. "Out of the fullness of the heart the mouth speaketh," and out of the fullness of the heart the hand worketh also. Action will come. Fill yourselves with the ideal; whatever you do, think well on it. All your actions will be
magnified, transformed, deified, by the very power of the thought.
