A positive state of mind is not merely good for you, it benefits everyone with whom you come into contact, literally changing the world.
Dalai LamaWhether we like it or not, we have all been born into this world as part of one great human family. Rich or poor, educated or uneducated, belonging to one nation or another, to one religion or another, adhering to this ideology or that, ultimately each of is just a human being like everyone else. We all desire happiness and do not want suffering.
