Existensialism Mystique

Jean Paul Sartre has a lot to answer for doesn't he?
Not given to us by God? So what was given mystery?
Need a purpose, perhaps we just had to decide our own,
any personal credibility and logic may be just unknown.  

I feel like an existentialist today, really, what to say,
so did you suddenly clutch belief out of thin air today?
Okay, if you're happy it's not something bought on ebay,
but when you come 'down,' remember not just a good lay.

It's finding satisfaction within your soul and being whole,
and not giving credit to unfounded fantasy and hyperbole;
never mind Jean, I'm sure that you had good intentions,
but didn't realise most of us don't understand your positions.

Now I know why I'm here - 'they' said that nirvana was near,
it's part of the plan - but admit the philosophy was not clear.
