>>15791860The Jewish people preserved the Mishna as an unwritten teaching for about 1,400 years. After the destruction of the Second Temple, the leading Sage Rabbi Yehuda Hanassi realized a long exile was about to begin, and that if the Mishna wasn't written down it would become lost. He thus took the unprecedented step of writing it down.
Not long after this, the leading Sages in Babylon again saw a decline in scholarship, so they wrote a more comprehensive explanation of the Mishna, called the Talmud.
Kabbalah is also part of the Oral law. It is the traditional mystical understanding of the Torah. Kabbalah stresses the reasons and understanding of the commandments, and the cause of events described in the Torah. Kabbalah includes the understanding of the spiritual spheres in creation, and the rules and ways by which G-d administers the existence of the universe.
