What I dream of is an art of balance, of purity and serenity devoid of troubling or depressing subject matter - a soothing, calming influence on the mind, rather like a good armchair which provides relaxation from physical fatigue. Henri Matisse
It is requisite for the relaxation of the mind that we make use, from time to time, of playful deeds and jokes. Thomas Aquinas
If a man insisted always on being serious, and never allowed himself a bit of fun and relaxation, he would go mad or become unstable without knowing it. Herodotus
Now this relaxation of the mind from work consists on playful words or deeds. Therefore it becomes a wise and virtuous man to have recourse to such things at times. Thomas Aquinas
A cheerful frame of mind, reinforced by relaxation... is the medicine that puts all ghosts of fear on the run. George Matthew Adams
