It is possible, as I have discovered, to be relaxed and restful in spite of any amount of physical turmoil without. For a person who has a busy schedule which makes great demands on his time, this is an invaluable thing to acquire, because you will be able to use your time in the best possible way without being disturbed by every little thing, by having your nerves jangled or losing your trend of thought, or, most disrupting, fighting against and resenting the noise and the interruptions.
