Brothers: 
Statue of Brothers on Wikipedia
”There is a destiny that makes us brothers;
None goes his way alone:
All that we send into the lives of others
Comes back into our own.”
Edwin Markham (1852-1940), U.S. poet. A Creed (l. 1-4)… Family Book of Best Loved Poems, The. David L. George, ed. (1952) Doubleday & Company….

After searching to find this brief quote in two different places, I decided to look in another of my books; The Best Loved Poems of the American People (also published by Doubleday) - and there, I found this second verse:
I care not what his temples or his creeds,
One thing holds firm and fast -
That into his fateful heap of days and deeds
The soul of man is cast.
