What is the eternal brotherhood of life?

All you can do is just to study your own heart and life―and see that never for a moment are you in any state, but that of love and sympathy toward the rest of the race―toward all other forms of life. 

From a horse to a rock, from a skyborn star to a tadpole, from a president to a murderer, we are all children of life, linked together, close as brain cells. 

We rise and fall together. No one can rise or fall alone. Never forget that. We belong to the eternal Brotherhood of Life. 

Call it God or Father if it suits you better. Life covers it. There is nothing dead anywhere.
