Astronomy, numerology, fad food cults, "dope" ( opium, morphine, and alcoholic beverages ) tarot cards, etc. for 100s of years, on and off, though mostly in Europe, for some of that, and not only amongst lefties.
The New England Fox sisters were at it, with "spiritualism" quite a few years PRIOR to the Civil War here!
Cagliostro was at it, in Europe, in the mid 18th century and had many an Aristo and Royal followers!
A LOT of that all was BIG all over America in the 1960s; NOT just in California! And it was also around in the 1940s and '50s, but more hidden from view.
OTOH...these things are NOT all that "BIG" in the general public, with most GenZers now.
It’s a fascinating history and California ended up with more than its share after 1900. Jack Parsons of Caltech, NASA fame was in the middle of it all.
“these things are NOT all that “BIG” in the general public, with most GenZers now.”
I noticed the same flaw in his approach. The writer’s perspective is limited by his focus on elite pop culture which feeds his belief, or perhaps his desire, that this tiny slice of our culture designs the rest of it.
Yoga might have gone away and later come back among the elites, but for the culture at large it simply continued to grow the whole time.
It’s important to keep in mind that pop culture trends, especially pertaining to areas like religion and music, have been orchestrated through the military intelligence wing of the occultist global cabal.
The cabal’s tentacles are firmly placed into internet discussions and are frequently activated to discredit statements like mine in this post.
