This study, using a descriptive-analytical method and relying on meta-roles of ideas, studies the way mystical experiences are represented in Sufi writings and seeks to answer the question of what effect does the dominance of each of the roles of language in these texts have on the way linguistic processes are used? The results of the study show that the dominance of each of the roles of language in these texts has directly affected the type of use of linguistic processes and has caused a difference in the representation of the experiences of Sufi writers.
