The woman in the article was withdrawing from Zoloft during a very stressful time and went to meditate for 10 hours a day. It is not a surprise she had a psychotic break.
Disregarding we have hidden memories that are locked away, it is established that our minds suppress troubling memories. After a long meditation time, they can come out.
In my personal experience, I have had to discontinue sessions due to bad memories arising.
That's enough on its own to cause the issues being attributed to meditation. That also tells us she had prior issues even though the article seems to be trying to place the blame solely on meditation.
Antidepressant withdrawal is nothing to mess with.
Very insightful comment, though I might point out that bad memories on their own don't inherently cause significant issues, it's in the the how/if one reacts to them.
