"God has created human souls for himself. He desires to unite them to himself and to give them the immeasurable fullness and incomprehensible bliss of his own divine life, already in this life. That is the goal to which he directs them and toward which they themselves should strive with all their might. But the way to it is narrow, steep, and difficult. Most people remain en route. A few manage to get beyond the first beginnings--a dwindling small number arrive at the goal. That is due to dangers on the way--worldly dangers, the evil enemy, and one's own nature--but also due to ignorance and lack of qualified guidance. Souls do not understand what is happening within them, and seldom is someone to be found who could open their eyes to what is going on."
