The t-shirt says, DANTIAN ARE THREE QI CENTERS THAT CONCENTRATE ONESELF WITH THE QI OF THE ONE which is the Qi of the Source of all of existence that underlies it. They are in the areas of the abdomen (Earth Dantian), heart (Heart Dantian), and brain (Heaven Dantian). They are represented by the green Earth trigram, Yin-Yang symbol, and Heaven trigram.
