Even in the highest of all worlds, fusion with the Divine is only by first enmeshing within Chochmah –– the power of nothingness. This underscores the idea that only something that is utterly surrendered to the Divine has the power to manifest the Divine. What has no identity other than being pure expression of the Divine will? These are the Torah and the mitzvot. And between the two of them, the effect of the practical mitzvah, in which even the power of the animal soul is subsumed within the Divine, is farthest reaching –– bringing Divine manifestation even upon the lowest elements of the worlds and ourselves.
