It is a basic Kabbalistic concept that the human soul is, in a manner of speaking, a spark of Divine revelation in the world and that each human being is a microcosm of the entire universe.
Chassidut shows how the rarefied teachings of the Kabbalah, which speak to the macro-universe, can be adapted into a structure with ethical and practical meaning for our individual lives.
In this way, Chassidut is a form of applied Kabbalah.
Just as the Revealed Law frames the behavior of our bodies, the internalization of Kabbalistic notions of the Hidden Law can attune us to our soul, educating it to connect with the Divine.
In this model, the power of Kabbalah is harnessed not to serve our own desires but to align them with the wishes of the Almighty.
