Still, we can all think of examples of people who thrive and are very happy under the most adverse conditions (the opposite is also the case). So, it would seem that people's capacity for happiness is, at the very least, extremely elastic: i.e it's not completely bound up in external conditions.
When the internal conditions/criteria congruently match the external conditions/reality, we feel one way.
When the internal conditions/criteria are incongruent and do not match the external conditions/reality, we feel another.
Perhaps its not the external or internal conditions that matter, but the condition of congruence (content free process)?
Any thoughts anyone?
