We know that we are happy when our mind is

We know that we are happy when our mind is peaceful, and unhappy when it is not. It is therefore clear that our happiness depends upon our having a peaceful mind and not on good external conditions. Even if our external conditions are poor, if we maintain a peaceful mind all the time we shall always be happy.
