The Jews are not a part of a vast Whole which they re-integrate in dying, but they are a Whole in themselves, defying space, time, life, and death. Can God be outside the Whole? If he exists, necessarily he confounds himself with this Whole...Thus Divinity in Judaism is contained in the exaltation of the entity represented by the Race - passionnel entity, eternal flame, it is the Divine essence. It must be preserved and perpetuated, therefore the idea of pure and impure was created.
