Analysis of the Growth Factors of Mystical Texts in the Middle Centuries (460-638)

The rise or fall of schools of thought is influenced by various factors. Looking at the history of the creation of mystical texts over many centuries, the quantitative and qualitative increase or decrease of these texts can be seen.Using the descriptive and analytical method and referring to historical reports, the present research seeks to answer the question of why the frequency of mystical texts has increased significantly in the historical period from 460 to 638 AH. What caused the growth of mystical texts in this period is the expansion of the Ash'ari school and their special attention to the "heart" as a practical tool in epistemology, which can be categorized under cultural developments. Although Mu'tazila school also continued this intellectual life, the dominance of some Ash'ari principles can also be seen in Mu'tazila's writings. Among these principles is "intuitionism and relying on the heart" as a tool of knowledge. The support of the Abbasid caliphs for this school was also in the process of its spread. The existence of a relationship between the leading scholars of this school with the Abbasid rulers or the rulers under their influence was also among the political reasons that greatly contributed to the expansion of the Ash'ari school.
