The dragon mentioned in ancient geomantic omen is actually a mountain range. Because of the breath of the earth, the movement and evolution of crustal organization shaped mountains. Form and qi are in harmony, and Jin Mu's five elements of fire, water and soil are matched. Earth is the master of the five elements, which is like "the meat of the dragon" and the mother of all things. Water is likened to "dragon blood", such as blood circulation, which is endless and is the source of all things. The metaphor of fire is "dragon's breath", which is a warm current in the mountains and dominates the changes of terrain and atmosphere. The metaphor of vegetation is "dragon's hair", which is born by nature. Metal stone is called "the bone of the dragon" and is the basis of breath operation. The dynamic gasification of mountains and breath belongs to yang, the soil belongs to yin, the soil nourishes breath, and the breath changes into a situation. The internal and external structures are connected by one vein and take care of each other.
The Dragon Cave mentioned in ancient geomantic omen is the place where the situation, structure and breath of the mountain gather. The function of searching for dragons and acupoints is to place the bones of ancestors in the hidden places of mountains, structures and smells, where the yin and yang are vaporized into one, and to communicate the gasification of natural smells by relying on the dynamic gasification changes of mountains, so that the bones can reproduce the changes of smells and senses. Due to the structure of mountains, the gasification of breath can be directly induced by the gasification in human body, and the gasification of ancestors' bones is related to the gasification of their descendants. Therefore, the famous tombs selected by predecessors are all built in places where the situation, structure and atmosphere of the mountain are hidden, and their atmosphere changes. This also witnessed the gasification change of Fengshui Dragon Point, and combined with the bones of human ancestors, it can play a very good role in the change of breath in future generations.
The way to find Longdong should be observed according to the change of mountain situation. The place where the vitality of the mountain structure condenses is the location of the Dragon Cave. The mountain is formed by the gasification of heaven and earth, and its potential is mainly gas, which needs gas to condense and form a knot. For this reason, the famous tombs selected by the former teacher are all in the places where the vitality of the mountain structure is condensed, conforming to the yin and yang in the ground and integrating the gas of the water source. Only when the qi in the cave is pure, and the yin and qi are gasified to form power, can the fruits of nature be harvested.
Mountains have veins, and water is active. The change of land atmosphere is dominated by the formation of mountains, and the change of situation atmosphere is dominated by the convergence of water sources. The metaphor of water movement belongs to Yang, and the metaphor of mountain belongs to Yin. When mountains and rivers intersect, it is the time when yin and yang merge. Only when the qi of Yin and Yang is gasified and constantly gestated can everything have life. Because the yin and yang in the underground are vaporized and condensed in the essence of the mountain structure. The smell of water source is vaporized and gathered in the environmental situation where the mountain structure is formed. The purpose of finding Longdong to bury the remains of ancestors is to harvest its breath and make it more vigorous.
