Mental health research revisits what saints and sages have known for years

Mental health has taken over the role of religion in society.

I'm reading through a paper on "well being", the neologism for positive
mental health. I came across this quote from a book by a significant
author mentioned in the paper.

"The point cannot be overstated: Every desirable experience—passionate
love, a spiritual high, the pleasure of a new possession, the
exhilaration of success—is transitory"

I reckon smarter people such as Jesus and Buddha or Marley and Gandhi
have said stuff like that in far more eloquent ways. Of course they had
a mental illness so had a huge advantage when it came to understanding life.

The problem is the teachings of the religious icons don't make it into
politics. It takes economics to justify "love thy neighbour" and
"there's more to life than money" and all that stuff. People look upon
it as if it's some new found thing but the saints, sages, prophets and
seers (and the female biological gender equivalents) have been speaking
this message throughout human civilisation.
