Our inner happiness and disillusionment reveal themselves in a variety of ways: physical tiredness and burn-out, inner disquiet and depression. In fact, often we experience a general sense of malaise that overwhelms us. Gordon MacDonald says, "Our private worlds are polluted with various kinds of spiritual smog and toxic air." After identifying these pollutants, the author points the way to freedom - the state of inner peace which restores our spiritual passions and gives us the means of maintaining inner balance.
