On the level of our souls, there is perfection. But in this physical world, there is no such thing as a person that is completely whole.One person may enjoy health; another person may enjoy happiness; another, wealth; and yet another, power. But in every single human being, there is a part that holds darkness. It is this darkness that gives us the opportunity to do what the kabbalists call our tikun—the process of correction in which we can overcome that part of us that is negative.
The Creator never promised that we wouldn’t have problems in our lives. There was never a promise that life would be one big party. That is not why we incarnated as we are. We incarnated so that we could overcome our darkness and through our effort transform it into Light for all.
