I love Yunus Emre The Turkish best poet about mystic poetries. I highly recommend: Get this book and read it. I am sure you 'll love him, too.
Generally when we think of Sufi and Hindu devotional poetry a small set of names come to mind - Attar, Rumi, Kabir, Mirabai ...; Yunus Emre is certainly not among those names although he deserves to be. He composed in a Turkic language, a language family noted for its love of language, its wordplay and doubling. This is poetry of the highest quality with a down to earth touch resonating with divine love imagery. A must read for anyone interested in religious poetry, bhakti poetry or Sufism.
