This paper examines the Rumi's Influence on Persian Literature and Islamic Mysticism. Jalal al-Din Muhammad Rumi, a preeminent 13th-century Persian poet and mystic, profoundly impacted both Persian literature and Islamic mysticism. His work, characterized by its deep spiritual insight and lyrical brilliance, revolutionized Persian poetic forms and themes. Rumi’s innovative use of the ghazal (lyric poetry) and masnavi (narrative poetry) set new standards in Persian literature. His ghazals, filled with themes of divine and earthly love, transformed the expression of emotional and spiritual experiences in poetry. The "Masnavi," his magnum opus, provided a narrative framework for exploring complex mystical ideas and became a seminal text in Persian literary tradition. In Islamic mysticism, particularly Sufism, Rumi’s teachings emphasized divine love and the quest for unity with the divine. His philosophy, centered on transcending the self to achieve spiritual enlightenment, became central to Sufi thought. The Mevlevi Order, founded by his followers, exemplifies his influence through its practice of the whirling dance as a form of spiritual meditation. Rumi’s writings, including the "Masnavi" and "Divan-e Shams-e Tabrizi," integrate allegory and parable to convey profound mystical and philosophical ideas, influencing the development of Sufi practices and beliefs. Rumi’s legacy extends beyond Persian literature and Sufism; his work has achieved global recognition and continues to inspire diverse audiences. His ability to articulate universal themes of love, longing, and divine unity ensures that his contributions remain relevant and celebrated worldwide. Rumi’s influence is evident in the continued reverence for his poetry and the enduring presence of his mystical teachings in contemporary spiritual and literary contexts.
