 If you add masters what's internal, then the external will be also mastered. This is balance of yin and yang. So the ancients knew that, understood that, is that you have to control your nervous system, control your heart rate even, your breath rate. And that in turn controls your thoughts and your mind and your consciousness. And from doing that, they were able to create or generate this frequency throughout the entire body and the mind that allowed them to self heal, allowed them to even unlock superhuman abilities and allowed them to increase the intuition and boost their luck.
