When we meditate, our whole body is in a state of extreme relaxation, and most of the main meridians in our body will not be oppressed by external weakness. It is very beneficial to the circulation of qi and blood in the body, and it is also beneficial to get through the meridians blocked by blood stasis in the body, so as to better make the qi and blood of the body smooth. At the same time, it can also relieve the deficiency of heart, lung, spleen and stomach, and also guide the downward flow of blood gas. It can be seen that meditation can not only nourish the kidney and brain, but also nourish the heart, lungs, spleen and stomach.
