Kneading clay to make a beautiful and useful pot is hard work, patience, determination, skill and experience but it's only the "nothing inside" this pot that gives us the use of the vessel.
SO WHAT!.... you may ask.
Open up your mind and empty it - somewhat - by dropping some of your cherish opinions, values, judgments and expectations. Only after this you will be able to create this "nothing inside" and use it as......an anti-stress weapon.
It is not easy but soon you will realize that your mind become quieter and more receptive. You will be able to carry your life and deal with your problems in a far more efficient way than you think.
