When we consider this question from a still deeper point of view, we shall find that in the spirit of brotherhood is hidden a way to illumination. A man who may live by great principles, or who prays all day or meditates in the caves of the mountainside, if he does not show the spirit of brotherhood, is no good to himself or to others, because brotherhood is the way to develop spirituality. It is not exclusiveness, it is not running away from the world which is the way of the really spiritual ones. Their way is to consider one's obligations, to keep one's word, one's honor, and to prove sincere in whatever minor capacity one may be working, faithful to friends and true to everyone. These are the merits which develop by themselves when the spirit of brotherhood has matured in man.
