There must be many separate people in the world, each of whom carries an elementary piece of common egoism. We are the consequences of our previous changes. As Baal HaSulam writes, there are no new souls in our world that are just beginning their development from the most elementary states.

Each of us carries very important information, and without it, there will be no complete correction, no perfect states of the soul—the creation. Everyone should understand their responsibility for the opportunity to advance the whole creation to the Creator by their own efforts, because without him it is unattainable.

Each person is not just a small particle striving toward the Creator and advancing the collective soul by a tiny millimeter, no! In spirituality, this is a much more complex and comprehensive movement. When a person works on uniting with others, they completely become that single soul created by the Creator.

Spirituality does not divide into parts, does not dissolve, and does not multiply. It gradually reveals itself to a person as an eternal, perfect, and unified state. Everything happens only to the extent that our perceptions are corrected.
