The poem was written by the American Poet and educator Henry Wadsworth Longfellow. One of his famous poems are “Paul Revere’s Ride” and “The Song of Hiawatha”. In his poem “A Psalm of life”, he urges people to think & act in the living present, and to get rid of depressed & melancholic thoughts about the unknown future and the buried past. He praises the eternal soul which does not slumbers, and he distinguishes it from the transient flesh which is made of dust (or clay) and becomes dust after death.
