I did the sense meditation in a nice place in nature. It did not last long and I felt quickly much more at peace. I then resumed my walk and at one point, for no reason, I stopped walking, bent to the ground and picked a four leaf clover. A little further, I heard a woodpecker and looked up the tree, knowing I had little chance to see the bird. But there it was! It made my day, really :-)
So thank you Jon!
