Mystical clothing is not just a determinate object on the subject's body. Mystical clothing is a living body that, in the act of hearing, confronts the subject with Dasein, and this occurrence of meaning reveals mystical implications of the existential. In the discourse analysis of this sign system, influenced by phenomenological views in Heidegger's Being-in-the-World and Dasein, Merleau-Ponty's theory of the body, and the reading of the discursive semantic sign; it passes through the structural aspect of the object of clothing, and therefore mystical clothing transcends the subject's consciousness as a phenomenal sign in adaptation to the body and perceptual situation. In this research, the phenomenological reading has addressed the structural, eventful, and fusional communication system between the subject's body and mystical clothing. Heidegger proposes Dasein as the meaning of being in the world and existential identity. The research problem deals with the analysis of the discourse of Dasein in clothing and studies how the perceptual subject occurs in fusion with the mystical garment. The results of this research state that the reproduction of Rumi's mystical thought in the nature of the garment and hearing has caused the epistemological occurrence of the subject, therefore, in the fusion discourse of perception, his original existence is opened to the universe and enjoys the essence of truth.
