Until a person begins to suffer because of his natural properties (pride, passion for money, power, bodily pleasures), until he feels ashamed because of them, until he sees them as an obstacle on his spiritual path, these properties cannot be perceived as good. We have to suffer our way through these feelings and realize that until we receive the strength from above to master our desires, we will not feel good. We cannot get rid of desires; we have to use them correctly. Without our desires, it is impossible to reach adhesion with the Creator.
