Pain may be the only reality 

but if mankind had any sense it would pursue the delusion called happiness.

 All the philosophers and poets who tell us that pain and suffering have a place and purpose in the cosmic order of things are welcome to them. 

They are frauds. 

We justify pain because we do not know what to make of it,

 nor do we have any choice but to bear it. 

Happiness alone can make us momentarily larger than ourselves.
