Yehuda Leib HaLevi Ashlag (1885-1954) is known as Baal HaSulam (Owner of the Ladder) for his Sulam (ladder) commentary on The Book of Zohar. Baal HaSulam dedicated his life to interpretations and innovations in the wisdom of Kabbalah, disseminating it in Israel and throughout the world. He developed a unique method to the study of Kabbalah, by which any person can delve into the depth of reality and reveal its roots and purpose of existence.
What is the most interesting he composed wondrous melodies that express all of his spiritual states during his study and teaching Kabbalah. This melodies can sounds to someone sad, but it isn’t so. To someone who listen them carefully they open his heart and deeply penetrate spiritual message passing the feelings of his great sage. In other words, they can elevate person to higher dimension than this we live in. This dimension is comprised of another worlds called in Kabbalah spiritual worlds, and by those melodies one can be for a moment in touch both with this worlds and heart of this sage, and feel what he has feltin the moment when the melody was composed.
The more sensitive listeners this melodies can elevate them very high, touching them to the very depth of their tiny point in their hearts what Kabbalists called the soul or in Hebrew neshama.
