virtuous cycles - feel good, do better things, feel even more awesome, repeat.
the second one is way, way harder. doing more awesome things gets increasingly hard. doing more destructive things is rather easy.
in economies, bubbles get inflated in virtuous cycles. when things come crashing down, they crash down really, really hard.
buddha tells us the way is to simply get the heck out of the cycle. are there bubbles that still get inflated? are there things that might get a buddhist come crashing all down? a discovery that's there's no reincarnation? there's no karma? buddha never existed? or that the buddhist way is somehow "proven" not to be the ultimate reality, and was in fact harmful?
but then... you can't actually "disprove" buddhism (or any other deity/religion for that matter).
