Double cultivation refers to the double cultivation of life, and sex refers to people's mind, thought, temperament, character and spirit. Life refers to human body, life, energy, fate, matter, etc. Double cultivation of life is also "double cultivation of spirit and body", which is generally the comprehensive cultivation of body and mind. In fact, human life is a double fusion of two kinds of life, namely spiritual life and physical life. People usually say to be physically and mentally healthy, and one of them is incomplete. Therefore, the word life highly summarizes the two major elements of life.

In addition, the technology of double cultivation comes from the double cultivation school, which changes psychology with physiology and physiology with psychology. The infirm and sick people start with life skills, refine qi to eliminate diseases and strengthen the body, and then settle down, refine the spirit, refine the spirit and return to deficiency, and improve the spiritual realm. People who are psychologically fragile or have bad behavior should start with sexual performance, refine their own foundation, eliminate selfish distractions, adjust balance, improve the level of pursuit, open their minds, and cooperate with taking medicine to exercise qi, so that their performance will be easy to test.
