I believe our happiness is based on our interrelationship with gravitational force i.e. our relief from it which consequently is the reason for it feeling lighter than unhappiness. Does anyone have an opinion?
I think that gravity impels us to live as our perception of relief from it provides us with the sensation of happiness while when it becomes more noticeable we are less happy. Our battle with this force is our primeval, subconscious purpose i.e. our spiritual quest for happiness.
