Anyone can meditate. It is a matter of learning to relax your focus on the present moment, for it is in that moment that we open space to access to our inner being, which is always receptive and joyous.
The mind tends to wander to the past & future,so the idea is to practice being here now. That can be done when walking, gardening, painting, dancing, even doing the dishes can be a meditation.
Focusing on the physical body is always a good place to start, so I always start with slow deep breaths, which draws your focus inward, flowing your life force energy through your entire body.
Deep breathing elicits the relaxation response, so that practice alone could be your entire meditative process. To get you started, try the meditation below which I wrote at the request of one of my students who said she only had five minutes a day to meditate. I recommend you say it outloud to yourself every day.
After each statement, take a least one deep breath before moving on. Don't skip this, as that is the part that opens the space for the magic to happen. This meditation actually morphed into a song one day, all by itself it seemed, and became the song Yes I AM on OM GAIA.
So, the purpose of meditation then is to stop the exhaustion of constantly DOING and consider just BEING for a moment or two, for it is in that moment that all of our unrealized potential awaits us.
