The heaven, the earth, and the great man are also big, because the human spirit is divided into three parts, corresponding to the image of the three talents of heaven, earth and human beings. The soul of life resides in the body and holds life, the soul of heaven corresponds to the clear spirit of the sky, and the soul of the earth corresponds to the turbid nature of the earth. The two souls of heaven and earth are always stationed outside. , Only the soul of life is fixed on the body! The two souls of heaven and earth are mixed together, and it is difficult to find traces; only the soul of life resides in this body, which can be used to seek the root of the Tao, cross the sea boat, and bridge to the other shore.
