This book is a collection of poetry by the 13th-century Persian Sufi mystic Jalal ad-din Rumi, or simply Rumi as he is more commonly known.
I went into this book expecting majestic, mysterious uniqueness; and I found it. Rumi, it is claimed at least by the blurb inside the Penguin Classics edition,* is the most-read poet in the contemporary United States of America - which I honestly found quite a shock given the friendly terms Iran is currently on with that country. I guess people who read poetry are generally more forgivingly open-minded? Anyway - the Penguin Classics edition, which I read, edits the whole of Rumi's multi-volume masterwork the mathnawi into twenty-seven thematic chapters, with themes ranging from Bewilderment, Emptiness and Silence and Being a Lover to Art as Flirtation with Surrender, Recognizing Elegance and Jesus. As a Sufi, Rumi believed that union with God in His divine loving nature was achievable to the willing a dedicated soul, and that belief shines through on every page of his poetry - there is an affirmingness there, a love of all that is human and authentic, almost to a fault. Many of these poems are tongue-in-cheek; lots are genuinely funny; many deal with profane matters; several are genuinely pornographic (there is one very graphically memorable one involving a donkey and a makeshift sheath); many more deal in explicitly religious terms with the struggles of human life and consciousness, of love and hope and loss and fear, of union and separation, of discovering and keeping one's place in the world or even simply of wondering where that may be. All are beautiful and worth reading.
I don't know enough about Sufism to confidently discuss my reflections on this collection of poetry in religious or spiritual terms, but as poetry, as pure voice that uplifts and echoes the human spirit, I can confidently say that this incredible man is worth reading.
