897 – First Stanza of William Blake’s “Auguries of Innocence.”

To see a world in a grain of sand
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.

686 – “To love somebody is not just a feeling—it is a decision, it is a judgment, it is a promise. If love were only a feeling, there would be no basis for the promise to love each other forever.

–Erich Fromm

–Ernest Becker
