Meditation doesn't bring psychological problems. If you already have then, it exarcebates them. Bring them more into focus. Don't start meditation practices if you have: Traumas, PTSTD, COD, etc. Meditation is the ultimate introspection practice. It's not a relaxation practive, though it can give that after effect. You will dive deep within yourself, and if you have some "monsters" stored deep, you will face them face to face.
"Some clinicians believe that meditation can cause psychological problems in people without underlying conditions, and that even forty minutes of meditation per day can pose risks. In 1975, The Journal of Nervous and Mental Disease published the case study of a thirty-eight-year-old woman, Mrs. M., who had no history of trauma or psychotic episodes but had begun to experience “altered reality testing and behavior” soon after taking up transcendental meditation. She was meditating for twenty minutes, twice a day. The authors, psychiatrists at the University of California, Davis, wrote that
an altered state of consciousness within days after beginning TM, and the occurrence of the “waking fantasies” shortly thereafter, leave little doubt of some causal relationship between the use of TM and the subsequent psychosis-like experience.
They concluded, “We would expect the occurrence of powerfully compelling fantasies in some portion of normal individuals utilizing depressive procedures of any form,” including meditation."
Most will disagree with me but: Those "waking fantasies" are the result of dilligent meditation. They occur because the brain activates some senses which aren't normally used. But as mainstream Science knows little about them, they're treated as "psychosis" and "fantasies". I can't say about her case specifically, but overall, I can assure you, they're not. But the thing is, the proof can't be shown. It must be experienced. I've been studying these things for years. I'm not a "blind believer". I've experienced them, as millions of others did. Dismissing these things as "fantasies" is naive at best.
They're sometimes referred to as "Extrasensory perception", that is the ability to perceive things using senses which are not the base ones. The things perceived by these extra senses can be excluded from psychosis if in a controlled experiment. For example. One person holds a card with a number in one room. Another person with these senses activated, can then perceive the number correctly a number of times higher or much higher than the chance margin. Several experiments have been made on these phenomenons (which are in fact natural) for decades, with a higher than average degree of success. There's several disclosed papers from CIA for example, describing them in detail.
Given that this was just a case study and we don't have explanations for why TM alone would cause this, it seems the simplest answer is that TM can exacerbate underlying conditions.
