The mastery of emotion, places the energy of the universe at your disposal. Man can only expect to be entrusted with great power by proving his ability to use it constructively and selflessly. Incessant vigilance over thought, action, and desire is indispensable to those who wish to make progress in the unfolding of their own being. The hand that slays must lift the fallen, while the lips given to cursing must be taught to pray. The heart that hates must learn the mystery of compassion, as the result of a deeper and more perfect understanding of man’s relation to his brother. The firm, kind hand of spirit must curb the flaming powers of emotion with an iron grip. In the realization and application of these principles lies the key of Developing Inner Strength.
