A Psalm Of Life and The tide rises,the tide falls
"A Psalm of Life" carries a message of hope and encouragement. It encourages people to live their lives to the fullest, using the short time we have here on Earth as a gift. The poem is a message to future generations to find work and action that gives them purpose and passion.
Death is literally everywhere in "The Tide Rises, the Tide Falls." The poem takes place at twilight (the death of the day), a traveler is seen leaving the shore for thelast time (he is dead by the end of the poem), and the speaker keeps telling us that, while the tide rises, it also falls (in a sense, it dies).
A Psalm of Life" carries a message of hope and encouragement; it basically says that although life is so short and so temporary, the fact that we do eventually die doesn't matter that much, because we can still live life to its fullest.
