With the power of faith, march on, march on! By daily meditation, never forget Him. Every day new vistas and new revelations of His presence will come to you. Strength will come; for His power is there. Acknowledge it firmly; let it sink calmly into the depths of your being. When by the science of controlling the life energy [Kriya Yoga] you master the subtle forces through which He creates and sustains all things, you will share in His dominion over all creation. - Paramahansa Yogananda.
