Joy has spiritual dimensions Pleasure pleases the physical senses while joy touches the spirit. A prime example of the spiritual nature of joy versus the physical nature of pleasure is in the union of a devoted husband and wife who love and respect each other. Sure, their union involves physical pleasure, but it is enhanced by a spiritual connection and joy that someone outside this bond will never experience with random acts and multiple partners. Even work, for work's sake does not always bring joy. The work you do that gives of yourself, the work in which you leave a bit of yourself behind is the most rewarding for everyone involved.
Pleasure is passive.
I'm not saying there is anything wrong with eating a piece of cheesecake or watching TV and movies. But, when you realize how precious life is, how short and fleeting, then you understand that when you spend too much time seeking pleasure, you sacrifice joy. Joy does require effort and that is probably the biggest reason why most of us avoid it. We don't want to put forth the work it takes to experience joy. Yet joy is worth any price.
