Peace of mind, tranquility

Just musing, but is tranquility or contentment the absence of emotion, the negation of equal amounts of positive and negitive emotions, or a singular emotion unique to itself?

it is a balance, but is also unique to itself... probably because it is rarely, if ever experienced.

I think tranqulity is the state in which your concious brain activity is reduced to a large extent. I don't think therz a 'emotion' called tranquility or that its the absence of emotion, tranquility is simply the reduction of brain acivity
