A form of mental concentration practiced over 2500 years ago in Asian cultures; was made popular in the West by Maharishi Mahesh Yogi as a means to help increase energy, reduce stress, and have a positive effect on mental and physical health; it involves the person sitting upright for 20 minutes, with eyes closed, and silently speaking a mantra (a key stimulus word used uniquely by each practitioner to return to the proper meditative state) whenever thought occurs.
