After human beings are born from their mothers and grow into adults, the “jing, qi and spirit” that constitute the original body of the human body will gradually be depleted, followed by the continuous decline of physiological functions, so various diseases begin to invade the human body, and so on. With the continuation of depletion, year after year, once the three treasures of “jing, qi and spirit” are exhausted, a person’s life will come to an end.
In order to get rid of the fate of death, the wise Chinese ancestors saying “我命由我不由天 “My fate is up to me but not the Heaven”. For this reason, our ancestors began to look for the method of immortality as early as the Yellow Emperor’s time. For thousands of years based on the empirical evidence of generations of longevity practitioners, they created a unique Chinese life-rebuilding technique – Neidan (Daoist Alchemy).
Inner alchemy is a treasure of Chinese Daoist culture and the crystallization of the wisdom of the Chinese nation to perceive the universe and life. It embodies the eternal pursuit of human life and is a set of all-around means of human body reconstruction. Neidan cultivation uses a series of methods to make up for the lack of essence in the human body, so that the human body can return to a healthy state without any diseases; then it further refines and sublimates people’s spirit, thinking and consciousness, and finally enables people to realise great wisdom and completely get rid of all kinds of troubles, and become a God-like figure (Xian) who is free between heaven and earth. This process is the four steps of refining the jing and transforming it into qi, refining the qi and transforming the spirit, refining the spirit to return to emptiness, and refining the emptiness and returning to Dao.
Daoist inner alchemy is a profound way of dual cultivation of life. Since ancient times, it has been secretly passed down among people who have fate, and some people who have successfully practiced alchemy in history are the envy of everyone. For example, Zhong Liquan in the Han Dynasty, Lu Dongbin in the Tang Dynasty, Zhang Boduan in the Song Dynasty, and Zhang Sanfeng in the Ming Dynasty were regarded as gods and immortals by the people, and even the emperor envied them.
