Research is showing the power of listening to and saying OM. The vibration made and felt when listening to and saying OM is said to have benefits for mental and physical well being. Gangadhar et. al research showed, "'Om' chanting indicates limbic deactivation. As similar observations have been recorded with vagus nerve stimulation treatment used in depression and epilepsy, the study findings argue for a potential role of this 'Om' chanting in clinical practice." (Gangadhar et. al., 2011 ).
