Figures of Speech and Poetry

"Poetic tools are a means to aid poetry, not an end in themselves' ******************************************************************* I don't understand why poet use poetic tools so often making a poem so tough to understand Hiding behind the garb of metaphor, simile, onomatopoeia, alliterations and other poetic tools the real thoughts of poet, the message he wants to convey never reaches the mind of readers Ask any school going child reading english literature he will say "I don't understand this poem what is poet trying to say! Why can't they make it simple? Why use figures of speech?" Why not call a spade a spade! Be simple straight and clear! Let your message reach others! Write such that each reader interprets the poem in same manner. Same meaning, same mental image gets created in reader's mind and poets and readers mind become one such should be poetry! I have read poems which no one one has understood, each reader giving his own interpretation. I don't understand what is the fun in that? Especially when you want to convey a message, use straight clear language as against poetry tools.
