Sitting still with your legs bent and feeling numb in your feet and legs just shows that the nerves and blood vessels in your feet and legs are not smooth, which proves that your health has potential problems. So let go of your legs and wait for the numbness to pass, but you have never experienced pleasure. If you persevere, you can sit on your legs with smooth blood and ensure that your legs travel to your back and whole body, you will have great pleasure, but you won't want to get down from your seat and loosen your legs.
In the past, western medicine criticized meditation, thinking that meditation legs crossed, blood vessels were pressed down, and blood circulation was not good, so it was numb. Speaking of vascular oppression, look at those people who are struggling to carry the burden, and the blood vessels on their legs are bulging one by one. That's because they exert too much force, so the blood vessels and nerves are injured and tangled. Meditation does not entangle the muscles in the legs. Western medicine does not understand the truth of Chinese medicine or even Taoism. Numbness has nothing to do with the obstruction of blood circulation, but because qi and blood are unclear and turbid qi has not fallen. After the pulse passes slowly, my legs are not only numb, but also very comfortable and I don't want to get off the seat. The so-called joy, including the meaning of pleasure, pleasure is still rough. (Teacher nan huaijin tells)
