The transformation brought about by Nima Youshij, who freed Persian poetry from the fetters of prosodic measures, was a turning point in a long literary tradition. It broadened the perception and thinking of the poets that came after him. Nima offered a different understanding of the principles of classical poetry. His artistry was not confined to removing the need for a fixed-length hemistich and dispensing with the tradition of rhyming but focused on a broader structure and function based on a contemporary understanding of human and social existence. His aim in renovating poetry was to commit it to a "natural identity" and to achieve a modern discipline in the mind and linguistic performance of the poet.
