“All this long human story, most passionate and tragic in the living, was but an unimportant, a seemingly barren and negligible effort, lasting only for a few moments in the life of the galaxy.”

Context: For the most part we humans live with the false impression of security and a feeling of being at home in a seemingly trustworthy physical and human environment. But when the expected course of everyday life is interrupted, we are like shipwrecked people on a miserable plank in the open sea, having forgotten where they came from and not knowing whither they are drifting. But once we fully accept this, life becomes easier and there is no longer any disappointment.

En último instante, toda mi vida durará un instante.

Context: Of course, the worst of all lives is the vicious life; the life of a man who becomes a positive addition to the forces of evil in a community. Next to that and when I am speaking to people who, by birth and training and standing, ought to amount to a great deal, I have a right to say only second to it in criminality comes the life of mere vapid ease, the ignoble life of a man who desires nothing from his years but that they shall be led with the least effort, the least trouble, the greatest amount of physical enjoyment or intellectual enjoyment of a mere dilettante type. The life that is worth living, and the only life that is worth living, is the life of effort, the life of effort to attain what is worth striving for.

Context: That which we say and do, if its effects last not beyond our lives, is unimportant. That which shall live when we are dead, as part of the great body of law enacted by the dead, is the only act worth doing, the only Thought worth speaking. The desire to do something that shall benefit the world, when neither praise nor obloquy will reach us where we sleep soundly in the grave, is the noblest ambition entertained by man.
It is the ambition of a true and genuine Mason. Knowing the slow processes by which the Deity brings about great results, he does not expect to reap as well as sow, in a single lifetime. It is the inflexible fate and noblest destiny, with rare exceptions, of the great and good, to work, and let others reap the harvest of their labors. He who does good, only to be repaid in kind, or in thanks and gratitude, or in reputation and the world's praise, is like him who loans his money, that he may, after certain months, receive it back with interest. To be repaid for eminent services with slander, obloquy, or ridicule, or at best with stupid indifference or cold ingratitude, as it is common, so it is no misfortune, except to those who lack the wit to see or sense to appreciate the service, or the nobility of soul to thank and reward with eulogy, the benefactor of his kind. His influences live, and the great Future will obey; whether it recognize or disown the lawgiver.
