In the process of training your thinking, you may experience constant change of thought, talking to yourself, lying to yourself, anxious, defecation disorder, nightmare, irregular eating, and so on, which may bring you an extremely hard time. Under this condition, the main principle is to be able to eat and sleep, and do not let the complex concept harm your mind and human body. By following this principle, the function of your concept may be reinforced in the long run. The phenomena you encounter when training your mind will extinguish after your concept is reinforced. A reinforced concept enables you to be all eyes and ears. You will be able to adapt to the changes around you, and solve problems easily. When you become all things to all men and adapt to the changes with ease, it means your concept is reinforced to the level that your sentient type can easily control your human body to deal with the changes around you.
