Spirituality provides multiple doorways of comfort and insight through wonder, prayer, and the true meaning of humility, worship, and sacrifice — a practical book for deep interior exploration.
Carl McColman has both studied and practised the Christian mystical tradition, stressing its earthiness and 'ordinariness'. He holds that mysticism is not an esoteric realm, reserved for the very holy, but is what all Christian life is about. I strongly commend The Big Book of Christian Mysticism.
