Illusions/false realities. = "maya"; gets in the way of us achieving our true goals - obstacle, that we have to overcome.     
     Pleasure & success exist, but they aren't really what you want...
     Analogy: dreams: they're real in the sense that you have them, but they aren't true reality. 

When you can become detached from yourself, nothing more than an observer of yourself, then you can achieve moksha. 

Joy ≠ pleasure.
