Everybody existing on earth must undergo the entire correction and also feel himself as a creature relative to the Creator. As the rest of the souls are corrected, we will all become united into a single general construction.
Therefore everybody who corrects himself corrects the whole world. In his or her attitude toward the world, a person corrects the entire world and prepares the world so that each of its other parts becomes corrected. This happens because a person is connected with the rest of the parts, meaning that having corrected himself relative to somebody, he exists inside the other, awakening that other for correction. Having said that, one must not wait for what will happen with the rest of the people, but act to correct himself.
