The mystical contents of Kabbalah are not necessarily restricted to sefirot and angels and other-worldly forces.
They are also in the familiar constituents and motions of the body, in the Bible and the Talmud, in all the many vehicles of the Torah.
To be sure, the truth cannot be found in the wrongness of things, in the hidden evil, no matter how deliciously secret, or in any mystery that is at once confounding and soluble.
Mystery or mystical experience may simply be the way one sees certain truths.
For some people the most revealed of Torah passages is full of secret meaning and wrapped in unfathomable mystery.
For others, even the most esoteric wisdom is bright and clear, with nothing mysterious about it.
The Baal Shem Tov used to say: The numerical value of sod (secret) is exactly that of or (light).
