Fairyland is understood as a transcendental existence in China traditional culture, and it is people's yearning for eternal life and perfection. Immortality is regarded as a metaphysical existence beyond mortals, which requires not only the cultivation of the body, but also the cultivation of mind, morality and consciousness. As a part of keeping in good health, deep breathing can have a positive impact on physical and mental health, but it is not the same as cultivating immortality.
It should be pointed out that immortality is generally considered to be beyond the laws of nature in real life, and the scientific community has not confirmed that human beings can truly achieve immortality through some means. As a fitness method, deep breathing still needs to be practiced on the basis of scientific and reasonable principles, and at the same time, it also needs to learn from traditional culture seriously on the basis of rationality to maintain its physical and mental health.
Generally speaking, deep breathing, as a health preserving method, is very beneficial to human health, but it can't directly make people live forever. Living forever is a deeper spiritual process. It should be noted that any statement about immortality needs to be skeptical and pay attention to health science.
