Ghandi

Here is a great quote I found...on a piece of paper in my box of papers...source: p.218.
But in what book? I do not know.

 Here is the quote:

 "When your mind is still, you can work hard and be active every day of your life and still be at rest, because you will not be working under the goal of personal ambition. That's the secret of Gandhi, who worked for a selfless cause fifteen hours a day seven days a week even in his seventies, but never got exhausted, because, he said 'I am always at rest.'
