More simply known as Rumi, his poetry was mostly written in Persian but popularized in many languages including English. I recently read The Love Poems of Rumi published in the United States in 2015. This collection was translated by world-renowned Iranian-American architect Nader Khalili, who was also an author and humanitarian and teacher.
Before then I had come across some of his poems and quotes which impressed me greatly. The love poems connect expressions of deep emotion to the very soul of the poet. Rumi’s full name is Jalāl ad-Dīn Muḥammad Balkhī which is a mouth full but I was intrigued why Rumi is most popular. Rumi’s birthday is commemorated on September 30.
