Transcendental meditation is a natural way to focus out attention deep into our minds, far from what we would consider the physical realm. The idea is to tap into the source of thought. When you focus your awareness like that, you can open the door to an altered state of consciousness.
Once you’ve achieved this, your breath becomes rhythmic, your heart beat begins to steady, your mind stills and your body relaxes. Brain scans of people in these states have revealed that the mind’s waves calm. Some report discomfort, others report the sensation of floating.
