Happiness is simply defined:
The absence of humanity's natural depression
That which binds all human life by rightful sorrow
For our disconnection with our mortal purpose
And our delusional yet rational will for the advent of tomorrow
No man, woman, or child deserves their next day
But the intangible emotion of God guides the way
So in that sense happiness isn't the absence of anything
Rather, our internal need to survive letting itself sing.
