The ultimate medicine is definitely one of the three talents. The wonderful meaning of creation is nothing more than two or five. When ordinary people start, they always start with the Shen Qi inflated enough. If the Shen Qi is fully inflated, the true essence will be born. If the true essence is generated, the Qi and Shen will be preserved. If the essence is exhausted, the Shen will fly. If the Shen dies, the Qi will disperse. Qi arises from the heart, and essence comes from the body. Knowing this wonderful meaning, you can return to the holy power, but your body and mind will be confused. Then this generation leads to the Tao, which is nothing more than this. Ni Wan said: Qi belongs to heaven, essence belongs to earth, and spirit belongs to human beings. The cover is made of the essence of human nature, then human beings are heaven and earth, and heaven and earth are human beings.
