Critical analysis of mystical discourse in Hafez’s sonnets; according to Fairclough's three-levels pattern and based on the interpersonal metafunction of language in Halliday’s systemic-functional linguistics

One of the effective methods to study the semantic aspects of mystical language in literary texts is critical discourse analysis, which is a new attitude of discourse analysis in linguistics studies that analyses texts considering sociocultural context. The present research analyses Hafez's mystical language with an analytic-descriptive method and based on Fairclough’s pattern and answers to this issue: How and why did Hafez create his mystical discourse and make it comprehensible? For this purpose, after describing Hafez's mystical sonnets according to Halliday’s systemic-functional linguistics framework and relying on the interpersonal metafunction of language in that framework, by observing the interlingual and extralingual contexts and with an intertextual analysis, it pulls out the reasons and explanations required from the beddings of his words and interprets and explains them ideologically. The results of the research indicate that factors performing the interpersonal metafunction in Hafez’s language are marked and discursive; they play an ideological role and are considered discursive features. The interpretation and explanation of these meaning features indicate that worldview, ideology, power relations and epistemological devices are the main effective factors in the formation and comprehension of Hafez’s mystical discourse. The achievement of the present research is to justify and describe Hafez's mystical language scientifically and pattern based and also to express how and why his mystical discourse is formed, produced and comprehended with applying effective and reliable instruments of critical discourse analysis. Therefore, the achieved results are based on linguistics authentic and reasonable rudiments and are also far from generalization and its following mistakes.
