Chinese medicine says that "the heart is full of lust, the god is full of food, and the god is full of sleep." Among them, "not enough to eat" is what we generally call "broken valley" now.

Strictly speaking, Pigu is practiced through strict kung fu. The body is full of energy, full of qi and blood, smooth meridians, carefree, energetic, and does not think about diet. Just like what Buddhists say, "don't eat in the afternoon" and "eat after meditation" are the same in the precepts of Baguange. It is the natural physiological response of the human body after entering a special state under meditation training, and the body and mind are synchronized with nature.

Just as meridians do not exist anatomically and belong to the human energy body, it does not mean that Chinese medicine is useless. Bigu can't be explained by modern western medicine, physics, chemistry and life science, and there is no mathematical model to describe it.

The special physiological state of human body is the special state of human body, mind and spirit. Coupled with the special psychological state such as energy phenomenon and meditation that can't be explained by modern physics, there is a special physiological phenomenon called "hungry".

Instead of discussing its scientific nature, we should make up our minds to practice it seriously and experience the feeling of this special physiological state.

As long as you practice the correct techniques carefully and have enough energy in your body, everyone can feel the wonderful feeling after your potential is infinitely stimulated.
