The methods of cultivating spirit include introspection, keeping quiet, keeping thinking and keeping unity. Popular before Wei and Jin Dynasties were all based on the theory that form and spirit depended on each other and form and spirit must stand. It is believed that all internal organs of the human body have gods, and all gods have surnames and colors. If these gods exist in human body, the body will be healthy, that is, if they exist, they can be safe and stable. However, due to the temptation of color, fragrance, taste and desire from outside, the god of human body is often tempted away. God left the form, that is, life left the form. If God does not protect his home (body), the body will be corrupted and life will die. Therefore, if you want to live forever, you must leave God in your body.
It is difficult to determine when the method of nourishing the heart began. As early as Laozi, Zhuangzi and Huangdi's Canon, the method of nourishing the heart was put forward. In Laozi, there are some expositions, such as "empty your heart, solid your belly", "empty your heart, keep your peace, keep your trust" and "flexible and capable of being a baby". The original Taoist classic "Taiping Jing" discusses in detail the methods of nourishing the heart and spirit, and holds that nourishing the spirit is the basis and premise of all health preservation. Ge Hong of the Eastern Jin Dynasty advocated the way of "keeping one" in the Inner Chapter of Bao Puzi, arguing that if you want to live forever, you must be quiet, quit addiction, be quiet and forget. However, the most systematic discussion on the way to cultivate one's self-cultivation should be the book On Sitting Forgetting by Sima Chengzhen, a famous Taoist in the Tang Dynasty.
The theory of "sitting and forgetting" holds that spiritual cultivation is a step-by-step process, and thus puts forward the seven-order theory of "sitting and forgetting with peace of mind": "religious belief" and "husband believes in the roots of Taoism and respects morality." "Only when the roots are deep can the road be long, and the roots can be prosperous." Broken edge. That is to say, it is required to "get rid of material desires and simplify things", to be isolated from all secular things and to remove the pursuit of material interests. "Close your heart." The rise of material desire is due to the existence of my perception, feeling and thinking consciousness. If I want to live forever, I must "close my door, close my door and be diligent all my life." Simple things. Everything outside the body is "a lecher, not a good medicine for health." Sun Simiao, a famous Taoist priest and medical scientist in the Tang Dynasty, thought that "if you want more, you will lose your wisdom". The storyteller must simplify things, but he can't stand the desire. "If you don't move or shake your essence, you can live forever." After accepting simple things, "True View" "calms down and idles around to see the truth clearly." "Tai Ding". After closing the door of the heart, we should be open-minded, stable, open-minded and not distracted by the outside world, that is, "the heart is uncertain, but it is uncertain." "get the order." At this point, it has reached the best state of nourishing the heart, not touching things, moving but not scattered, and can't afford it. In another book, Tian Yin Zi, Sima divided the specific cultivation methods into five processes: fasting, being prepared for danger in times of peace, forgetting to sit, and realizing Tao, which made the practice method of quietism more perfect and systematic. This is about the method of cultivating spirit.
