How to explain "human law, earth law, heaven law, Taoism law and nature"? Thank you.

If one practices the earth and the heaven, there is no need for Zen. I don't want to be original. I tell you everything is natural. "People abide by the law, abide by the law, abide by the law, and be natural." These four sentences are not only the law of being a man and doing things, but also the law of cultivating truth and proving truth. This is a secret language that is difficult to spread through the ages, and it is also the essence of Laozi's thought. The so-called "law" can be used as a verb, meaning imitation and learning. How to define earth, heaven, Tao and nature? Since ancient times, many people have expounded and explained this, but they stand in different angles and their understanding can be said. However, no one has really analyzed it from the research and practice of human life science. From the point of view of repairing truth, Ling Xuan's Law of Truth holds that the true meaning of these four sentences is the four stages of returning to nature, which directly explains how people return to nature and how people merge with nature, and profoundly reveals the law of repairing truth through highly summarized and incisive language. This theoretical system of congenital Dafa can be divided into five stages: "My mother, human land, human heaven, human Tao and human nature". If analyzed from the inside of the work, it can also be called: "I am law to my mother, man is law to the earth, God is law to heaven, fairy is law to Tao, and saint is law to nature." This explains the difference of cultivation level and grade in more detail and accurately, and describes the process of the integration of man and nature from acquired to innate and from low to high.
