The reader has before him the first biography of Rûmî written in the Spanish language. There are authors who only become famous thanks to their written works; outside of them, they do not exist. This is not the case of the Persian Sufi poet and scholar Mawlânâ Rûmî. Rûmî (1207-1273), in addition to being one of the most inspired voices not only of Islamic mysticism but of universal spirituality, was a precursor of the Sufi school of the whirling dervishes, famous for their hypnotic circular dance, about which Rilke would say that "it is the authentic mystery of the prostration of the person who kneels from within." Who really is this poet and sage of Sufism, acclaimed today by multitudes throughout the world? How was the transition from a sober and sober Muslim jurist to a drunken celebrant of the mysteries of divine love? The expert Islamologist Halil Bárcena tries to answer these questions, not only delving into RümI's vital singlatura, but also offering us the interpretative keys to understand his vast poetic work. The reader has before him the first biography of Rûmî written in the Spanish language, whose author, the Islamologist Halil Bárcena, is perhaps the greatest expert on him in the field of our language.
