An entire generation now regards Nirvana as its version of the Beatles. They are of course hopelessly mistaken, but I would not recommend you tell them so.

...it was not simply a matter of musical taste; whether you preferred the Beatles or [the Rolling] Stones said much about your personality and character. People who were happy, intelligent, well-adjusted, popular, clean, decent and punctual tended to be Beatles fans. Those who were evil, cretinous, scabby, drug-ridden, filthy, criminal perverts liked the Stones.
As for your author, I personally take no side in the controversy, remaining strictly neutral.

That great menacing Easter Island face.

Samsara is one flower. Nirvana is another flower. Enlightenment happens when both the flowers blooms.

In pursuit of Nirvana you may not know what your question is but you will know for sure when you hear an answer!

We cannot thin our way to nirvana.
