We can influence the state of the body through thought. We are sad - tears appear, we are nervous - pressure rises, etc. It is necessary to take this fact into account and use it to maintain the normal functioning of the body.
Our body consists of many organs and systems that are firmly connected by the nervous network, with which we can control our body. The "control center" of our body is the brain, it is responsible for many processes in the body.
But the main thing that controls us is thoughts. It would seem that what thought means, because it is immaterial? But look, you thought about sad things, and tears are already appearing in your eyes, which are quite material and tangible. Through them, we can control the various processes taking place in our body. This process can be called psychosomatics.
Most physical ailments result from improper circulation of energy in the body. A disease can tell us what we are doing wrong, why this ailment arose. So, for example, the cause of such a widespread disease as oncology is undercurrent of resentment and anger, digestive system disorders about intense fear, etc.
Usually, an ailment affects the most vulnerable areas in the human body, as they say, where "thinly, there it breaks." We can heal ourselves, just reconsider your way of thinking. As they say, the cause will disappear, and the consequence will disappear.
