“I am content; that is a blessing greater than riches; and he to whom that is given need ask no more.”

Abençoem-se antes um ao outro, é quanto basta, pudessem ser todas as bênçãos como essa.

Dichoso el árbol, que es apenas sensitivo,
y más la piedra dura porque esa ya no siente,
pues no hay dolor más grande que el dolor de ser vivo,
ni mayor pesadumbre que la vida consciente.
Cantos de vida y esperanza (1901), "Lo fatal" ("Fatalism")

Context: And the angel's body was bared, and he was clothed in light so that eye could not look on him; and his voice grew louder, as though it came not from him but from heaven above. And the angel said:
I have learnt that all men live not by care for themselves, but by love.
It was not given to the mother to know what her children needed for their life. Nor was it given to the rich man to know what he himself needed. Nor is it given to any man to know whether, when evening comes, he will need boots for his body or slippers for his corpse.
I remained alive when I was a man, not by care of myself, but because love was present in a passer-by, and because he and his wife pitied and loved me. The orphans remained alive, not because of their mother's care, but because there was love in the heart of a woman a stranger to them, who pitied and loved them. And all men live not by the thought they spend on their own welfare, but because love exists in man.
I knew before that God gave life to men and desires that they should live; now I understood more than that.
I understood that God does not wish men to live apart, and therefore he does not reveal to them what each one needs for himself; but he wishes them to live united, and therefore reveals to each of them what is necessary for all.
I have now understood that though it seems to men that they live by care for themselves, in truth it is love alone by which they live. He who has love, is in God, and God is in him, for God is love.

The Tragic Sense of Life (1913), VIII : From God to God

2013, Commencement Address at Ohio State University (May 2013)
Context: I don’t pretend to have all the answers. And I’m not going to offer some grand theory – not when it’s a beautiful day and you’ve got some celebrating to do. I’m not going to get partisan, either, because that’s not what citizenship is about. In fact, I am asking the same thing of you that President Bush did when he spoke at this commencement in 2002: “America needs more than taxpayers, spectators, and occasional voters,” he said. “America needs full-time citizens.”
And as graduates from a university whose motto is “Education for Citizenship,” that’s what your country expects of you. So briefly, I will ask you for two things: to participate, and to persevere.
After all, your democracy does not function without your active participation. At a bare minimum, that means voting, eagerly and often. It means knowing who’s been elected to make decisions on your behalf, what they believe in, and whether or not they deliver. If they don’t represent you the way you want, or conduct themselves the way you expect – if they put special interests above your own – you’ve got to let them know that’s not okay. And if they let you down, there’s a built-in day in November where you can really let them know that’s not okay.
