Han Yu Xiaotian paid more and more attention to the way of heaven and earth runes. He had a vague guess in his mind. The pattern of heaven and earth runes is also an important part of the road of heaven and earth, which will play a vital role in his own road of seeking Tao.

Therefore, although Han Yu Xiaotian has never been involved in Qimen dunjia and Zhouyi eight trigrams, when he saw the eight trigrams array diagram that Han Yuyi was studying, he was immediately attracted by the way of symbols and patterns involved.

At this time, Yuan Lao, standing next to them, suddenly said, "the eight trigrams array is called the nine palaces and eight trigrams array. Nine is the extreme number, and the number derived from the six trigrams and three trigrams is taken. Yi Youyun says that one's life is two, two begets three, and three generates all things. There is also the saying that Tai Chi gives birth to Liangyi, Liangyi generates four phases, and four phases generate eight trigrams, and the eight trigrams change into sixty-four trigrams. From then on, the changes are endless. "

"According to the ancient Chinese folklore, the eight trigrams originated from Fuxi, the head of the three emperors and five emperors. The Fuxi family began to draw the eight trigrams in guatai mountain, Tianshui, and opened up the sky with one drawing. The eight trigrams represent the Yin and Yang system of things themselves. One represents Yang and the other represents Yin. According to the changes of yin and Yang in nature, eight different forms are formed. Each hexagram represents a certain thing. Qian stands for heaven, Kun stands for place, Xun stands for wind, earthquake stands for thunder, Kan stands for water, Li stands for fire, Gen stands for mountain, dui stands for Ze. The eight trigrams are like eight infinite invisible bags, which contain everything in the universe. The eight trigrams match with each other and become 64 trigrams, and all kinds of heaven and earth are derived! "

Seeing that Han Yu Xiaotian and Han Yuyi seem to understand their own words, old yuan nodded slightly and then said, "according to the collection of my ancestors of Hanyu family, the original data of the recorded eight trigrams is the book of changes of the Western Zhou Dynasty, which contains 64 hexagrams, but there is no image. The hexagram of the eight trigrams is a word of understanding meaning, which is from GUI to divination. GUI, referring to Tu GUI, began to measure the sun and shadow with clay columns. Divination means to measure. To measure the shadow of the sun in the eight trigrams is to sum up and record the sun shadow observed from the four main points and four corners, which forms the image of the eight trigrams.

The basic symbol pattern of the eight trigrams is Yao, and each hexagram has three strokes, representing the three talents of heaven, earth and man. The celestial part is the whole celestial body movement and the meteorological change, these astrology, the ancient name astronomy; the earth part solves the whole process of growth and accumulation; the human part contains all kinds of human beings.

The essence of the book of changes is to regard heaven, earth and human as a whole, and to connect things of different quality and state together to explore the law of their operation. The unity of numbers, principles and principles is shown through the forms. The number, the reason and the natural heart are the same. As Lu Jiuyuan said, "my heart is the universe, and the universe is my heart.". Grasp the heart, you can feel the world, a thorough understanding of life. "

Yuanlao finally concluded: "the eight trigrams and Taiji diagram, to some extent, can represent the ultimate truth of Chinese traditional belief Confucianism and Taoism:" Tao. ". All things in heaven and earth, all the stars in the universe

In a short period of time, Yuanlao's explanation of "Tao" from another perspective seems to open a new door for Hanyu Xiaotian. Hanyu Xiaotian's eyes, which had been pondering with Han Yuyi, became a little dull.

"Taiji gives birth to Liangyi, Liangyi generates four phases, and four forms generate eight trigrams. The eight trigrams change into sixty-four trigrams. From then on, the changes are endless."

"Qiantian, kundi, Xunfeng, Zhenlei, kanshui, Lihuo, Genshan, Duze."

Yuanlao's words are constantly surrounded by the ears of Hanyu Xiaotian.

"My heart is the universe, and the universe is my heart. Grasp one's heart, one can feel heaven and earth! "

Like a bolt from the blue, Hanyu Xiaotian falls into the state of Epiphany again.
