Now that you have opened your heart to the light of Divine Truth, and have not resisted the flow of Divine grace into it, you should consider it your duty to also endeavour consciously and persistently to investigate the Teachings, so that your mind also may comprehend them. Personal effort is indeed a vital prerequisite to the recognition and acceptance of the Cause of God. No matter how strong the measure of Divine grace, unless supplemented by personal, sustained and intelligent effort it cannot become fully effective and be of any real and abiding advantage.
