A reluctant follower of Nima Yushij, Mehdi Akhavan-Sales published his "Organ" (1951) to support contentions against Nima Yushij's groundbreaking endeavors. In Persian poetry, Mehdi Akhavan Sales has established a bridge between the "Khorassani" and "Nima" Schools. The critics consider Mehdi Akhavan Sales as one of the best contemporary Persian poets. He is one of the pioneers of free verse (new style poetry) in Persian literature, particularly of modern style epics. It was his ambition, for a long time, to introduce a fresh style to Persian poetry.
