Each of us lives many lives, during which the soul experiences the desire to rise above the difficulties and return to its root. But along with that it senses the objection of the body and the environmental conditions to its process of development. That objection is meant to develop in the soul the ability to correct itself and rise to its root by overcoming the obstacles.
Man’s goal is to reach the root of his soul while still in the world, in his body of flesh.
