Here you will find the Poem A Pinch of Salt of poet Robert Graves
When a dream is born in you With a sudden clamorous pain, When you know the dream is true And lovely, with no flaw nor stain, O then, be careful, or with sudden clutch You'll hurt the delicate thing you prize so much. Dreams are like a bird that mocks, Flirting the feathers of his tail. When you seize at the salt-box, Over the hedge you'll see him sail. Old birds are neither caught with salt nor chaff: They watch you from the apple bough and laugh. Poet, never chase the dream. Laugh yourself, and turn away. Mask your hunger; let it seem Small matter if he come or stay; But when he nestles in your hand at last, Close up your fingers tight and hold him fast.
