Another essential thing is that those who do embrace the Faith should be constantly urged to study the literature of the Cause. It is not sufficient that our numbers should increase, we want people whose faith stands on a rock and no trial can move. We want people who will in turn arise and carry the Message to other people and guide other souls.
