Transcendental meditation (TM) involves sitting with eyes shut for 1520 minutes twice a day while saying a mantra. The practice has several advantages for mental health but, until now, it was unclear how those effects came about.

TM differs from other meditation practices in that it does not require concentration or visualization.

Instead, TM practitioners come up with a mantra, which is a word or phrase that has no real meaning.

The practitioners silently think this mantra, allowing the mind to naturally transcend, while both the mind and body remain awake, yet relaxed.

Most people can learn TM in a few months, and benefits from regular practice may include reduced feelings of stress and anxiety in a persons everyday life.

Research has found some evidence of this. A 2013 study, appearing in Military Medicine, listed TM as a feasible treatment for post-traumatic stress disorder (PTSD) in active-duty military personnel.

Similarly, a study appearing in The Permanente Journal in 2014, concluded that a TM program was effective in reducing psychological distress in teachers.

A 2016 study from the same journal found significant reductions in symptoms of trauma, anxiety, and depression in prison inmates who practiced TM.

With benefits seen in a relatively short period, one field of study has dived deeper into TM to find out exactly how it helps.

Now, new findings published in Brain and Cognition point to measurable functional effects in the brain of TM practitioners.

The study took place in the Molecular Mind Laboratory of Italys IMT School for Advanced Studies Lucca and involved 34 participants.

Of the volunteers, 19 had to complete two 20-minute TM sessions a day for 3 months one session in the morning and one in the evening.

The remaining 15 participants continued with their usual daily routines.

At the beginning of the study, the researchers used psychometric questionnaires to measure how well each participant could handle stressful situations.

All participants also underwent a functional magnetic resonance imaging test (fMRI) to assess brain activity and functional connectivity between various areas of the brain.

At the end of the 3 months, each participant underwent another fMRI test and filled in the questionnaires again.

After 3 months, the participants who practiced daily TM perceived feeling markedly less stress and anxiety.

Specifically, following TM practice, the group of meditators reported a reduction in psychometric scores reflecting perceived depression, anxiety and stress in opposition to resilience and social skills, the authors write in the paper.

Results from the fMRI scans also showed that the reduction of anxiety levels is associated with specific changes in the connectivity between different cerebral areas, such as precuneus, left parietal lobe, and insula, which all have an important role in the modulation of emotions and inner states, says first author Giulia Avvenuti.

However, none of these changes [were] observed in the group that did not practice TM, Avvenuti points out.

Pietro Pietrini, study coordinator and IMT Schools director, says these findings raise further questions about the link between the brain and the mind.

The fact that [TM] has measurable effects on the dialogue between brain structures involved in the modulation of affective states opens new perspectives for the understanding of brain-mind relationships, he says.

The results may also indicate just how quickly TM can have a tangible effect on the brain and the feelings of individuals.

Organizations such as the David Lynch Foundation which co-funded the study encourage people with trauma or individuals who experience high levels of stress in work and education environments to practice TM.

The organization will likely use the results to amplify their work across the globe.

This work adds to the growing body of evidence in support of this form of meditation. It also raises other questions.

As Pietrini explains, his teams findings extend the results of recent research suggesting that drug therapies and psychotherapy leverage on the same biological mechanism.

Future research may, therefore, look at different ways of targeting these biological pathways.
