Consecration is the consummation, when the Light has illuminated all the parts of your being, with a central will acting on the feelings, impulses, thoughts, emotions, activities, directing them always towards the Divine and when you move no more from darkness to light or from falsehood to truth or from misery to happiness but from light to more light, from truth to greater truth, from happiness to increasing happiness.
