Man’s entire human history is a generation-by-generation evolution of the will to receive, promoted by three factors: envy, desire and the pursuit of glory.
The reason for all the suffering in the world is the will to receive; therefore, suffering will bring man and the whole of mankind to the decision to leave it. Those whose will to receive has evolved enough will receive a push from Above to want something beyond this world. That push makes man begin to search for the source of satisfaction for this new desire, until the right teacher is found. It often takes years, and sometimes an entire lifetime is not enough. But if the Creator brings one to a place where Kabbalah is taught, it’s a sign that one is given a chance from Above to correct one’s soul and attain the goal.
