"A Prayer for My Daughter" by W.B. Yeats is a poem that expresses the poet's fears and hopes for his newborn daughter. The poem begins with the poet walking and praying for his daughter, in the midst of a storm. He imagines the future and hopes that his daughter will be granted beauty, but not so much that it makes her vain and lose her natural kindness. The poet also hopes that his daughter will be learned and wise, but not so intellectual that she forgets to be kind and compassionate. He warns her against the dangers of beauty, citing examples of Helen of Troy and other women who were ruined because of their looks. The poem ends with the poet wishing for his daughter to be like a "flourishing hidden tree" that dispenses kindness and love without expecting anything in return, and lives a life rooted in love and joy.
