Many introductory books have been written about the Kabbalah in recent years. Some of them aim at superficially deciphering the main concepts of a practically impenetrable subject; others seek to describe the way in which the mystical teachings were transmitted through the most famous Kabbalists of the different generations, dwelling on anecdotes and fables; others, finally, reduce their field of study to dubious comparisons between mystics and esoteric thinkers of different religions. In all cases, the honest person who has read any of these introductions to the Qabalah is left with the feeling that he has not taken even the smallest step on the path of Truth. Unlike the books so far published in the Spanish language, El Canto del Alma is not an introduction to the Kabbalah but a study manual. Its author, Rabbi Yechiel Bar Lev, who himself wrote a monumental commentary on the book of the Zohar, defines El Canto del Alma as a study manual that enables one to enter into the world of the Zohar and other Kabbalistic books with adequate and responsible preparation, whoever devotes himself fully to its pages with intellectual rigour and a large dose of humility and modesty. It is not surprising, then, that this book, in its original Hebrew version, is the most widely distributed manual in Torah study centres in Israel. El Canto del Alma is a gift from Heaven for minds and souls thirsting for truth.
