Every day, we are supposed to meditate in the morning for an hour. I'm not good at sitting still to do that, so a couple of days ago, I went for a walking meditation. In my mind, I sung a mantra pretty much the entire time, walking up a mountain road.
Now, this mantra is really powerful -- it is the one that I use which brings star visitors to heal people's physical ailments.
At one point, my guides directed me out onto some land (with a great view!), and showed me the effects of doing this meditation outside. A counter-clockwise vortex of golden light emanates from this meditation, and helps to heal the earth. So if I do the mantra as I walk, I am healing the earth. As I walked back down the hill, the soles of my feet seemed to have suction cups to the ground. This made it a bit harder to walk, but I could 'see' the trail of golden light behind me.
You can do this, too! Focus on a mantra as you hike.
