Not necessarily. There are two points of interest here. First, it depends what one means by meditation. If that’s mindfulness meditation, there are studies that have shown that it doesn’t deactivate the DMN. If we add here the fact that some people dedicate 4-8 hours per day to meditation that’s a recipe for disaster as the ruminating network is working all those 4-8 hours under the hood. There is a useful post by Gary Weber, mindfulness meditation—religious vs secular—does it work? - new research that discusses this point.
Second, if the shift has occurred without the proper preparation (i.e. the “I” is not deconstructed enough) or suddenly during the insight practice, the DMN network might try to win control back and there will be a conflict as the DMN is not shut down. That might happen if awakening happens “out of the blue” and the ruminating network is strong. That might even lead to the Dark Night of the Soul. Here is another useful post by Gary, Dark Night of the Soul?...who/why/what to do.
The key point in both is that “I” has to be deconstructed enough, which means one has to learn to shut down the DMN properly. As even after awakening it might cause trouble if one didn’t learn to shut it down. A book by Suzanne Segal, Collision with the Infinite is an example how a person might struggle to integrate awakening after it occurred.
So in the end I would guess (and please keep in mind that it’s a speculation of a layman) that given the proper conditions it’s not meditation itself that causes psychosis but the DMN that is hyperactive. The issue with mindfulness meditation is that it doesn’t address the activity of the DMN.
I also would like to clarify a point about mindfulness meditation and insight practice (vipassana). As they are sometimes mixed together. And while insight practice works, mindfulness, a stripped down version of it, doesn’t.
I’ll start by referencing a paper mentioned in the post, namely “Meditation experience is associated with differences in default mode network activity and connectivity.” [7] There the authors have shown that Theravada monks clearly shut down the DMN by what they call “mindfulness meditation”. And describe three methods of mindfulness meditation: breathing meditation, Choiceless Awareness (the term coined by Krishnamurti Jiddu), and loving-kindness (metta) meditation.
That might confuse things a bit. But let’s look at the basic source for monk’s training—Pali Canon. The basic instruction for insight and concentration practices in the tradition of Theravada is Satipatthana Sutta and Anapanasati Sutta which are unfortunately translated as “The Foundations of Mindfulness” and “Mindfulness of Breathing”. The word “sati”, which is translated as “mindfulness”, literally means “recollection”. And it is a term there that is used in developing concentration.
What do those texts say about practice? Is it only recollection of breathing and awareness? No. They are clearly set to contemplate the Four Noble Truths, the Five Hindrances, the Seven Factors for Awakening and so on. So they are loading contradictions in thinking to contemplate upon (e.g. “I suffer” / “Freedom from suffering is the goal”, “I feel desire” / “Desirelessness is the goal”, etc.). I would suggest that those act as koans to contemplate during practice. So both concentration is developed (samatha) and insight is cultivated (vipassana). In one practice!
So what does it say about the monks from the paper? First of all, they have selected monks who are awakened (who can switch off the DMN). Knowing the protocol of their practice they most likely have come to awakening through insight and concentration practices. And after that they can naturally abide in this place by just about any stimuli. But for the monks “mindfulness” means long-long years of vipassana and samatha practices. While for researchers it means the stripped down version of it (without accounting for the details how they reached that state)!
Long story short, mindfulness practice as noticing thoughts and sensations and coming back to awareness on itself seems to be not enough to shut down the DMN. It has to be full scale insight and concentration practices as described in the text (i.e. going through all the truths, factors, contemplating them, releasing attachments, etc.). And that’s what monks from the paper supposedly did.
There is a good video with one illuminating comment (pinned), Does Mindfulness Lead to Persistent Nonduality? In the comment it is said that the traditional vipassana practice by itself has a missing component:
He [the Dalai Lama] essentially gave his blessing to the Goenka retreats but said he felt that there was a missing element. He advised practitioners to look back and try to find the one doing the meditation.
So basically the Dalai Lama recommended self-inquiry practice on top of vipassana.
Why I decided to articulate those nuances? I feel like most of the time people confuse mindfulness meditation with insight practice and do it for years (I did so myself). I hope that clarifies things a bit.
Does this model conflict with the reasonably-common claim that meditative practices can trigger psychosis in some people?
