A study published in Psychological Reports showed that after 3.5 months of practicing Transcendental Meditation (TM), most of the 34 tertiary-level students at Maharishi Institute (MI) -- all of whom were initially diagnosed with PTSD by mental health professionals -- went below clinical thresholds as measured by standard assessments. Students also experienced relief from depression. A comparison group from University of Johannesburg (UJ) with the same diagnosis received no treatment and showed no change in their symptoms.
