What is the difference between mantra meditation and Transcendental Meditation?

Transcendental Meditation, or TM, is one specific, trademarked form of mantra meditation taught through certified teachers, using a personally assigned mantra and a set routine. Mantra meditation more broadly is the wider practice of using any repeated sound or phrase to focus the mind, which you can do freely on your own. So all TM is mantra meditation, but not all mantra meditation is TM. StillMind offers accessible mantra-style guidance you can practise anytime, without a formal course.
