There is a saying: "The method of geomantic omen is to get water first, followed by hiding wind." He also said: "The mountains are regardless of water, and the plains are regardless of wind"; "Tibetan wind is the highest in the mountains, and water is the first in the plains."
For example, in the Book of Burial, it is said, "The burials are angry", "The qi is scattered by the wind ...... The ancients gathered to make it last, but they stopped doing it", and "It is also for the land to stop the accumulation of qi and transform everything into life".
it can be seen that the purpose of "hiding wind" is to achieve the purpose of "gathering gas".
Tibetan wind and gas accumulation are rooted in the understanding and requirements for choosing settlement conditions. In fact, regardless of the flat land and high mountains, in the era when "thatch, branches, bamboo bundles and vines" are the main building materials, the ability of "thatch, branches, bamboo bundles and vines" to resist natural cold is extremely limited, and it is the top priority to choose a terrain that is sheltered from the wind and keeps warm. With the sheltered and warm terrain, everything becomes prosperous, orderly, relaxed, safe and auspicious. Up to today, although the development of science and technology has made it obvious that building materials have the ability to overcome and counter natural disasters, people still appreciate the concept of storing wind and gathering gas.
the place where the wind is hidden and the gas is gathered should be meandered by the mountains, winding up and down, and arching at different levels. Crowd forward without coercion, and you can gather without being abrupt. Come to the mountains to condense, stop and gather, and yin and yang are harmonious. The layer is thick, with deep water gathering and lush vegetation. In a word, this is an angry place with mountains, winding water, mountains circling and abundant vegetation.
one of the important functions of the ideal model of geomantic omen is to keep the wind from escaping, or to hide the wind, with the ultimate goal of keeping the vitality of the small environment (or gas field) from being lost. Because anger is the root of all things, the loss of anger means the loss of "vitality" in the environment around the cave field, and the loss of vibrant environment is the performance of "disaster".
