Torah speaks in the languages of stories, legends, the Talmud, Midrash, and statutes. The language of Kabbalah itself, is a complete formula, with maps, drawings, and an essence. The Kabbalah employs pure, mathematical, categorical laws in order to express spiritual phenomena. There exist many methods to describe what man senses and feels. The language of Kabbalah is a very refined method, very scientific.
Spiritual feelings are also possible to transmit with the language of music.
We do not know the music that the Kabbalists composed in the past. Nonetheless, the Kabbalists expressed feelings of the spiritual world through song and music. Also if a person had never seen anything in spirituality, he is able to feel a little what the Kabbalist felt at that moment in the spiritual world.
