The so-called foundation, as the name implies, means to lay the foundation. As we all know, the key to high-rise buildings is to lay a good foundation. Only when the foundation is laid can the building be built. If the foundation is not solid, even if the building is built, it will collapse.
The cultivation of Taoist Qigong, like Gai Lou, also needs to lay a foundation. The basis here mainly refers to two aspects: first, under the guidance of the master, stop loss of refining gas (male) and blood (female); The second is to dredge and repair the pathological changes of the body with the true qi (life energy) formed after the essence and blood are transformed into qi.
