One of the problems people have with getting themselves to meditate is that they can’t relax. If this is you, or if you simply want to get better at it, then try this:
Before beginning your meditation, in order to more easily establish a quiet and relaxed state, do something physical. This will use up some of the excess energy that keeps you (and your mind) from relaxing. Once you’ve done this, you will probably find it much easier to relax.
take a walk
walk the dog
do some stretching
What works best for you and how long you do it is up to you. Experiment until you get an idea of what best suits your needs.
Whatever activity you choose to do, pay attention to your body as you do it. By being mindful, paying attention to what you are doing, you add potency to your movement and will need only a few minutes.
Namaste (I bow to the divine one that You really are),
