How is harmony achieved?

Spirit-lives have no disappointments that grieve. 

Love here [in the world of spirits] is not disappointed. 

Those who are meant for each other always come into loving companionship. 

Even circles are drawn together by mutual sympathy and love. 

Yet not an alien thought—not an unwise criticism—not a word, question—or look—which is not in accordance and sympathy with the rest. 

So it is that spirit-lives help each other—so it is that their plans grow more perfect—so it is that in varying suggestions, in the varieties of study and knowledge, in helping each other, harmony is attained.
