When G-d’s unity is revealed in the mind and heart of men, this world becomes an abode for G-d; He is revealed there just as one reveals himself completely in his own home. Being thus imbued with the awareness of G-d’s true unity, he will be able to overcome any obstacle hindering him from carrying out the mitzvot. For how can anything stand in the path of G-d’s will—the mitzvot—when there is nothing in the world apart from G-d?
