This paper presents a detailed analysis of the development of mystic poetry through dividing its evolution into three eras. To this end, initially, the first era signifying the age of creation and growth of this trend is briefly examined . The paper, than, proceeds to discuss the second era with particular emphasis on the three prominent poets of that interval, Shah Nematollah Valli, Mohammad Shirin Maghrebi, and Shah Qasem Anvar.

More specifically, the stimulus behind this section of the paper is to pursue why this trend in mystic poetry faded away, despite its heydays when those poets lived. Finally, to be more objective, a corpus including ten lyric verses from each of the abovementioned poets is analyzed at linguistic, rhythmic, and rhrtorical levels.
