Ahmad Shamlu discovered the inner characteristics of poetry and its manifestation in the literary creations of classical masters as well as the Nimai’ experience. He offered an individual approach. By distancing himself from the obligations imposed by older poetry and some of the limitations that had entered the Nimai’ poem, he recognized the role of prose and music hidden in the language. In the structure of Sepid poetry, in contrast to the prosodic and Nimai’ rules, the poem is written in more "natural" words and incorporates a prose-like process without losing its poetic distinction.
