Happened to have a source on hand from my current study, because I'm compiling a book critiquing Old Calendarism. So, the article I'll share isn't on this topic, but it is discussed at some length.
I'll pull out a few relevant bits;
St. Barsanuphius gave a talk on the subject saying,
"He (Fr. Benedict) was given several tasks to perform by the elder—among other things, to find out if the Jesus Prayer was being done in monasteries. He travelled to many monasteries and convents and came to a sad conclusion: this most necessary prayer has been abandoned almost everywhere, especially in convents. Those who are still doing it are like candles that are almost burnt down.
Earlier, it was not only monks who did the Jesus Prayer—it was also done without fail by people in the world (for instance, the famous historical figure Speransky did the Jesus Prayer and was always joyful, despite his many labors). But now even monks regard this labor distrustfully. For example, one might say to another, “Have you heard?”
“What?”
“Fr. Peter has begun doing the Jesus Prayer.”
“Really? Well, he’ll probably go out of his mind.”"
Fr. John Romanides talking about a similar phenomena in Greece,
"It [hesychasm] was persecuted because the countries in which it had flourished started to become Westernized politically as was the case in Russia after the reforms of Peter the Great and in Greece after the revolution of 1821…
The Franks knew full well that they had correctly identified hesychasm as the source of Orthodoxy’s strength. So what did they do to get rid of it? After the Revolution of 1821 and the founding of the Modern Greek State, the Franks deliberately set out to undermine hesychasm, and Adamantios Korais took it upon himself to do just that. After the revolution of 1821, Korais declared war against hesychasm at the same time that the Russians and the Europeans were also setting their sights at undermining hesychasm and uprooting it from the Christian tradition. This is how we have reached the point where today we consider hesychasm to be an unimportant detail within Orthodox tradition and an insignificant phenomenon from the past.
In fact, we learned from the textbooks that we used in junior high that hesychasm is a heresy, a trivial and marginal tradition…"
The Nastol’naia Kniga [Handbook frin 1913] has an entry on Hesychasm in a section dedicated to “Schisms, Heresies, Sects, Etc.” informing us that
“a group of monastic mystics in Greece in the fourteenth century distinguished by the strangest reveries. They honored the navel as the center of spiritual energies and, consequently, the center of contemplation; they thought that, by lowering their chin towards the chest and gazing at their navel, they would see the light of Paradise and rejoice in seeing celestial inhabitants.”
The entry concludes by telling us that, happily, the
“nonsensical opinion of the Hesychasts about the means of the apprehension of the uncreated light was soon given over to oblivion on its own” …
