Peace of mind is the key to our overall wellbeing. It is directly related to happiness and inner peace. The more peaceful and calm our mind is, the less stress is perceived by our delicate mind and thus healthier and stronger our mind becomes.  Om is the basic sound of the universe; chanting it helps us temporarily dissociate from our worries  thus decreasing our stress burden.  Let us try out some OM chanting. It just takes a few minutes a day.
