Transcendental Meditation (TM) is a practice developed by Maharishi Mahesh Yogi, involving the silent repetition of a private mantra for 20 minutes twice daily. Practitioners sit comfortably with eyes closed and are encouraged to gently return their focus to the mantra when thoughts arise. Advocates claim TM promotes stress relief, creativity, efficiency, and physiological benefits, with some suggesting it leads to higher states of consciousness. However, scientific research on TM's therapeutic benefits has faced criticism for methodological weaknesses and potential bias. While some studies suggest TM may help reduce blood pressure, a comprehensive meta-analysis indicated it performed no better than other meditation techniques for psychological variables, and conclusions about its effectiveness in preventing cardiovascular disease remain uncertain due to limited and potentially biased research.

The technique involves a standardized course taught by certified instructors. Mantras are assigned individually, with the belief that their specific sound vibrations resonate with the practitioner. The selection process, described as mechanized by the Maharishi, is considered crucial for achieving the promised results, with different mantras potentially suited for different lifestyles or temperaments. The mantras themselves are often described as ancient sounds from Vedic tradition, chosen for their phonetic qualities rather than explicit meaning, though some interpretations link them to deities or specific vibrational influences.

Transcendental Meditation is practiced for twenty minutes twice a day, typically while seated comfortably with closed eyes. The core of the technique involves the silent, effortless repetition of a mantra, which is a sound or word chosen for its vibrational quality. Practitioners are instructed not to actively suppress thoughts but to gently redirect their attention back to the mantra when they notice their mind has wandered. This process is described as natural and easy, aiming for a state of relaxed awareness. While some practitioners report feelings of serenity and balance, others note it does not necessarily lead to profound self-insight. The TM organization emphasizes an 'open attentional stance' rather than focused concentration. The practice also includes a process termed 'unstressing,' which combines relaxation with spontaneous imagery and emotion.

The selection of a mantra is a key element in Transcendental Meditation, with the Maharishi reportedly standardizing this process. Mantras are assigned to individuals by trained TM teachers, often based on personal interviews, age, and gender, though specific methodologies have been debated. The mantras are believed to be ancient sounds, often from Vedic traditions, chosen not for their literal meaning but for their specific sound value and vibrational resonance with the individual. It is thought that the correct mantra harmonizes with the practitioner's nature and life, creating a soothing influence. The Maharishi cautioned that using incorrect mantras could be detrimental, suggesting that certain commonly found mantras might encourage withdrawal from life. The secrecy of the mantra is also emphasized to ensure maximum benefit and avoid confusion.

Proponents of Transcendental Meditation claim a range of benefits, including stress reduction, enhanced creativity, improved efficiency, and positive physiological effects like lowered blood pressure and reduced risk of heart disease. They also suggest the practice can lead to higher states of consciousness. However, scientific research into these claims has yielded mixed results. Methodological criticisms, including confirmation bias and varying theoretical approaches, have been raised regarding studies on meditation in general. Meta-analyses have found TM to be no more effective than other meditation techniques in improving psychological variables, and its efficacy in preventing cardiovascular disease remains unclear due to limited and potentially biased research. Nevertheless, some systematic reviews have indicated that TM may be effective in reducing blood pressure compared to control groups.
