 The soil that you walk upon has a certain sense of intelligence and memory. So even if you happen to live in a concrete jungle, it is important to keep in touch with the earth upon which you live, with your bare hands and bare feet. See, particularly the palms and the soles if they come in touch with the earth on a daily basis at least for a few minutes. A certain harmonizing of the physiological process will happen just being in contact with the earth. If you spend at least a few minutes in your garden barefooted, touching plants or trees, because this is the basis of your life, all life, yours and every other creature has come out of this earth. Stay in touch with it and harmonize your system.
