I play jackstones to relax and rejuvenate: I hold one stone in one hand with 4 stones on the floor, then I throw the one stone in the air and before I catch it I grab off the floor as many of the 4 stones as I am able to then catch the one stone too.
Playing jackstones is the simple joy of enjoying the agile exercise of my hands and enjoying focusing attention like meditation on my hands and stones instead of focusing on my struggles and sufferings.
While playing jackstones I am simply enjoying being alive, and I am happy.
