I came across this meditation a couple of months ago, and I just love it. It helps to ground and clear out all the ‘gunk’ from your energy ~ without tiring you out. I wouldn’t listen to it while driving, but there is very little risk that it will put you to sleep unless you are tired and needing a nap anyway.
I listen to it almost every day, and on some days a few times. I have shared it with a couple of clients, but for anyone looking for an awesome Grounding Meditation that will walk you through this process, I highly recommend this one.
