A recent study on long term Sahaja Yoga meditators/practitioners was recently done
To investigate regional differences in grey matter volume associated with the practice of
Sahaja Yoga Meditation.
Twenty three experienced practitioners of Sahaja Yoga Meditation and twenty three non-
meditators matched on age, gender and education level, were scanned using structural
Magnetic Resonance Imaging and their grey matter volume were compared using Voxel-
Grey matter volume was larger in meditators relative to non-meditators across the whole
brain. In addition, grey matter volume was larger in several predominantly right hemispheric
regions: in insula, ventromedial orbitofrontal cortex, inferior temporal and parietal cortices
as well as in left ventrolateral prefrontal cortex and left insula. No areas with larger grey mat-
ter volume were found in non-meditators relative to meditators.
The study shows that long-term practice of Sahaja Yoga Meditation is associated with larger
grey matter volume overall, and with regional enlargement in several right hemispheric corti-
cal and subcortical brain regions that are associated with sustained attention, self-control,
compassion and interoceptive perception. The increased grey matter volume in these atten-
tion and self-control mediating regions suggests use-dependent enlargement with regular
practice of this meditation.
