The Zohar is a foundational work of Jewish mysticism, known as Kabbalah. Written in the late 13th century by the Spanish-Jewish mystic Moses de Leon, it is primarily a commentary on the Torah, exploring the nature of God, the universe, and the soul. The text is composed in Aramaic and is structured as a mystical narrative, featuring discussions among various sages. The Zohar emphasizes the importance of understanding the hidden meanings within the scriptures. It introduces concepts such as the Sefirot, which are ten attributes through which God interacts with the world. The work has significantly influenced Jewish thought and spirituality, inspiring countless interpretations and studies over the centuries.
