The science of Kabbalah is based on the existence of only two forces: receiving and giving. The entire universe, the whole world, is based on them. Kabbalah is the equilibrating system between these two forces, leading them to the middle line.
The search for the middle line, its stabilization, its balance, at all levels—from zero to absolutely integral, complete, permanent, infinite egoism—is the subject of the science of Kabbalah.
It is a purely applied science and practice, which is necessary for us in order to get rid of the contradictions. Moreover, these contradictions are not theoretical, between something or someone, but between the creation and the Creator, that is, between us and Him.
We need to balance these contradictions, bring them to a common denominator, to the so-called middle line, where we and He will completely coincide in our desires, intentions, and actions.
This is how we will become partners, lovers, in an embrace, fused with each other at all possible levels, in all forces, desires, and actions.
This is the purpose of creation, which is called Dvekut, that is, a complete merger between two completely opposite forces.
