The highest righteousness of all...

...Is there any deed in the world that would be nobler than service to the common good? Is there any greater blessing conceivable for a man, than that he should become the cause of the education, the development, the prosperity and honor of his fellow-creatures? No, by the Lord God! The highest righteousness of all is for blessed souls to take hold of the hands of the helpless and deliver them out of their ignorance and abasement and poverty, and with pure motives, and only for the sake of God, to arise and energetically devote themselves to the service of the masses, forgetting their own worldly advantage and working only to serve the general good.
