Body, mind, and soul. Since ancient times, many philosophies, cultures, and scriptures related to these three aspects. For a chi master, these three aspects are the fundamentals of cultivating chi.
It is true chi can be produced through body vitality. However, this is only the beginning. As the cultivation continues, the user will notice it also affects the mind and soul. If someone wants to become a true master of chi, they not only need a strong body but also a strong mind and soul.
This is common knowledge for anyone who dabbles in chi cultivation for a long time. This leads to another conclusion: if someone could strengthen body, mind, and soul, their chi will also become more powerful.
Unfortunately, this kind of state is not easy. As humans keep practicing, they soon realize many difficulties. One of the most challenging things is to train one soul.
