What’s the difference between different types of meditation, like “mindfulness meditation,” “vipassana,” and “Transcendental Meditation”?

In Vipassana meditation, you’re taught to cultivate a quality of mind called “mindfulness,” which is simply a state of clear, non-judgemental, and undistracted attention to the contents of consciousness.

Transcendental Meditation is an example of a concentration-based meditation practice, where you develop the ability to focus on one particular sense object (like the breath) at the exclusion of all others.
