This paper is a comparative discussion of the epistemology of Divine Love in the poetical works of two mystics: Rumi and George Herbert. These two poets, who respectively come from the Islamic and Western traditions, neither share the same culture nor the same time, yet their concept of divine love is very similar. A comparative study of this concept in Rumi's Mathnawi and Divan and Herbert's The Temple will reveal the universality of Divine Love. The paper starts with the definitions of divine love through briefly examining the philosophical background of the theme of love in the Western and Islamic traditions, and will, then, proceed with the analysis of the poetical works of the two poets. The main reason for this amazing similarity lies in the nature of this experience, the love for the Absolute, which all men have felt in all times and places regardless of their national and cultural heritage.
