Some literary critics have often engaged in debates on the degree of overall cohesion and coherence across the couplets of the Hafez ghazals: some maintain that the Hafez’s ghazals lack coherence; some others believe that there is cohesion and coherence in the nature of the couplets. This paper presents an analysis of the overall coherence in a ghazal of Hafez- that has a weak cohesion apparently- by using a linguistics framework laid out by Halliday and Hasan (1976 & 1984). Based on this theory, although cohesion is an important property of a text, just finding the cohesive elements does not show that the text is coherent. Rather, after finding these elements, it is necessary to show coherence in a text based on Cohesive Harmony. After doing this analysis, we have found that this ghazal has a very high cohesion and coherence. So, by utilizing this theory - that is a scientific method-  we can probe the degree of  cohesion and coherence in any ghazal of Hafez or other literary texts quantitatively.

The study of text cohesion is a linguistic tool for understanding the structure of Persian literary works based on objective and accurate descriptions using a single model. In this paper, verses from Sanai’s Hadiqat al-Haqiqah (The Walled Garden of the Truth) were studied using the theory of text cohesion by Halliday and Hassan in systemic linguistics and the results were presented in diagrams. According to this theory, cohesion has grammatical, lexical and relational devices each of which includes more detailed devices. The purpose of this paper is to analyze each of these cohesive devices in Sanai’s Hadiqat. The research method is descriptive and each of the cohesive devices is investigated by mentioning couplet samples and their repetition frequencies. The results show that among the various types of cohesion, lexical cohesion, especially contrasts, and relational cohesion, especially causal relationships, have the greatest effect on the cohesion and integrity of the verses of Hadiqat.
