The mystery is not beyond and away from us. It is our destiny. "The fate of the world depends upon the mystery." Our task is to adjust the details to the whole, the apparent to the hidden, the near to the distant. The passionate concern of the kabbalist for final goals endows him with the experience of surpassing all human limitations and powers. With all he is doing he is crossing the borders, breaking the surfaces, approaching the lasting sources of all things. Yet his living with infinite does not make him alien to the finite.
