Kabbalah zu Bereschit 13:7

All this happens if (the soul) merited to amend the body in this world and overcome the power of that cursed being, (the Evil Inclination, which is Lot) until it is separated from it. As it is written, "And there was strife between the herdsmen of Abram's cattle (the soul) and the herdsmen of Lot's cattle, (the Evil Inclination)" (Gen. 13:7). Because in this world, on each and every day, those camps and rulers from the side of the soul are in strife with the camps and rulers from the side of the body, and they fight with each other while all the parts of the body are trapped in agony between them, between the soul and the serpent, between those forces that fight each other every day.
