Pleasure

There is a vast difference between pleasure and happiness. 

Pleasure can be the realm of the addicted. Pleasure is a momentary experience which depends on a stimulus. The stimulus can be the self, another being, an environment or a substance.

Happiness is a sustainable state of ongoing being. It is a form of consciousness, developed with practice and maturity. While it depends on being in the moment with joy, happiness is not dependent on the stimuli of any given moment. I can be happy while in pain, while also being disappointed, while also embracing sadness. 

Practice is a method for developing sustainable happiness. Humanist practice is a method of developing sustainable happiness while also striving to help others to do the same.
