During meditation, the brain is very busy!
At the same time, however, you may experience a great deal of relaxation and repose. The paradox is: you can’t relax without letting go of tension ... and in letting go of tension you remember all the things you were tense about.
Relaxation, tension, relaxation, tension.
Whatever thoughts, sensations, or emotions you have been holding back by staying tense are suddenly free to flood your awareness -- and be dealt with. Meditation is a highly alert state, and so you often find yourself shifting every few seconds between delicious rest and anxiety, until your system works out just the right balance between ease, excitement, and alarm.
This is what makes meditation ideal for managing the challenges in your life, including your relationships and your health.
