Another hindrance provided by our modern way of living is that it breeds haste, tension, pressure, and strain. These attitudes he carries from his daily routines into his meditation and thus spoils the practice or dooms it to failure. It is useless to approach such a delicate exercise with a demanding spirit which wants all the results all at once, with a haste which is better suited to the racetrack or the busy store. Success in meditation can only be had by discarding such attitudes and by sitting down to it with a willingness to give steadfast patient reverent effort which is not disappointed if the goal is not quickly reached.
