The theory that the immortal is noble and pure is the core purpose of Taoist belief, which embodies the distinctive characteristics of Taoism. The so-called "way to become immortal" means that Taoism pursues immortality and enlightenment. Taoism believes that immortals can learn and exist, live happily, and are immortals. They are all people who really learn the aisle, and they are the personality images of people who learn the Tao and the Channel. The important content of becoming an immortal is to achieve long-term vision through self-cultivation and cultivation. Therefore, Taoism teaches people to cherish life, to be reborn, to enjoy life, to improve the quality of life to the level of immortals, and to achieve the goal of integrating life with Taoism, that is, to gain the Tao.

Du Fu once summarized this message as: "Immortal Taoism is life-long, while human beings are infinite".

Taoism believes that through cultivation, people's material life can be continued, their spiritual life can be sublimated, and eventually they can become immortals. Therefore, in the pursuit of immortal belief, Gao Zhen in past dynasties actively explored the way of life cultivation and summed up rich cultivation theories and methods. Inspired by the spirit of "My life belongs to me, and I don't belong to heaven and earth", I am determined to "be kind to myself and others", which reflects the Taoist attitude of attaching importance to life and enjoying life.

To cultivate Buddhism and even to live forever is to ask people to live with a positive and detached attitude towards life. Human life is transformed by the spirit of heaven and earth of Tao, which is hard-won and should be cherished more.
