Introduction Based on Fairclough's approach in discourse analysis, narrative texts can play an important role in recreating cultural, political, social structures and producing meaning. "Behjat Afza" is a long story by Mohammad Mahdi Jorbadghani in the Safavid period, which has a transcendental texture in its structure. By examining the linguistics of Behjat Afza story, the underlying and hidden layers of the text, i.e., the state of the relationship between power and ideology during the period of Shah Abbas I and Shah Safi, are revealed. The text is analyzed in three layers: description, interpretation and explanation. The basic hypothesis of the research is that in the story, a discourse rules, worthy of the power and social status of each of the characters. By examining this story on the three levels of Fairclough's model, it became clear that the different use of words, the use of different linguistic and grammatical aspects, the difference in persuasive methods, the views of the characters in the story about each other, and the openness and covertness in the speech are directly related to the difference in the role of power in this story. The purpose of critical discourse analysis is to clearly analyze the structural relations of dominance, discrimination, power and control that are revealed in language. Methodology In this study, according to the research topic, the two descriptiveanalytical and library methods have been used. First, with the library and documentary method, the target texts were collected by referring to the Latin texts of discourse analysis, especially Fairclough's opinions, and translations in this field. In the next step, based on the three levels of description, interpretation and explanation, the story of Behjat Afza was analyzed according to the analytical method appropriate to the topics of discourse analysis and the main component, that is, power. In the second level, i.e. meaning interpretation, attention was paid to intertextuality and texts similar to this story, and in the third level, historical topics corresponding to the concept of power were explained.. Discussion Behjat Afza can be a good linguistic mirror of the 11th century. A language that is a mixture of popular phrases and interpretations as well as old words and phrases. The prose of this work is simple and in some cases ambiguous and obstinate. From among the three prose styles of the period, i.e. simple, artificial and complicated, and intermediate (average) prose styles, Behjat Afza's prose can be considered as intermediate prose. The text begins with the praise of the Lord, the Prophet and Imam Ali. Then, customarily, the author praises the two Safavid kings and mentions the historical events that happened during the time of these two, and the bravery of the Safavid kings in the battles. After that, he explain the reason for wrting the book, and finally starts the story. The three main elements of discourse are "text, interaction and social context", and in the critical analysis of discourse it is necessary to distinguish between the three stages of text description, interpretation of the relationship between text and interaction, and explanation of the relationship between interaction and social context (Guderzi, 78:1388). Conclusion One of the main components of critical discourse analysis is "power" because what forms the equations between societies is undeniablly the power. The extent to which individuals benefit from power advances or ceases their position. People are considered powerful or not, according to the degree of connection and relationship they have with him who has the most power. In Behjat Afza's story, the Safavid system has the largest share of power. Since Badiozaman is a representative of the government, he also has great power in using words and sentences, the manner of addressing others and expressing demands. Khaqan-e Chin (Emperor of China) also exerts the most power in his speech and actions throughout the stoty, but when he talks to Badi-o-Zaman, he chooses a paternal tone, because Badi-o-Zaman also represents the Safavid Shah and the land of Iran. Badi-o-Zaman conducts the important mission that the goverment emphasizes (expansion of the Shia religion) and finally it is Badi-o-Zaman who imposes his power on Khaqan-e Chin; Khaqan and his daughter convert to Islam and the Shia religion. The use of different aspects of the verb is also directly related to the power of people in the story. One of the most important social issues in this story is the view of women; there is no directness and authority in the words of the women of this story, except for Dalaleh, who also fulfills the role to unite Badi-o-Zaman to her lover, Parizad, by observing all aspects, and because of this, she sometimes feels more powerful, which is evident in her expressions. What is evident is that the powerful men of the story are always clear in expressing their wishes. Based on the results of this research, it is clear that Mohammad Mahdi Jorbadghani, the creator of Behjat Afza, paid a lot of attention to the component of "power" and consciously followed the appropriate criteria in creating the characters of the story.
