Sufism is a special School of thought which was formally introduced from the second century AD. The first thing that was important among them was the denial of the world and then, love for God was the ultimate goal of their deeds. Therefore, their teachings are divided into two categories: educational literature and romantic literature. Subsequently, the great heritage left behind which was nourished from this School of thought. Therefore, in this essay, the manifestation of the Sufi poetry in Persian literature will be investigated, without paying attention to the romantic poems written by non-mystical poets who mean human love for mankind, which have been whispered by the mystics in a certain way. Meanwhile, the attempt will be made to mention the masters of Persian Sufi poetry.
