What is the role of mantra in Transcendental Meditation compared to other forms of mantra-based meditation?
In Transcendental Meditation (TM), the mantra plays a central and specific role. During TM practice, practitioners silently repeat a personalized mantra given by a certified teacher, usually for 20 minutes twice daily. The mantra serves as an object for focus that helps to effortlessly transcend thinking and reach a state of deep rest and relaxation.

In other forms of mantra-based meditation, the use of mantras can vary greatly. In some traditions like Japa Meditation or Loving Kindness Meditation (Metta), a mantra is used as an aid for concentration, positive affirmation, or to cultivate specific mental states. The form and frequency of mantra repetition can also differ significantly among these practices.

In summary, while the use of mantras is common in various forms of meditation, the role and application of mantras in Transcendental Meditation are unique due to its emphasis on transcending thought rather than focusing on concentration or visualization.
