Practice.
Not for everyone. You need a source of pain. Constant. Focus on the pain. Start noticing its small changes. Get used to it. Then look at the clock. You will see how every two minutes the pain changes. It hurts more or less, the type of pain changes.
Sorry.
Maybe you will find another real example of the reflection of two minutes on the body. I only have this one so far.
Wu Xing and Ba Zi in practice.
As an RGM, I meet many people who do not know Wu Xing and Ba Zi, but use their knowledge from past lives. For example, people with DM Yin Fire who use only push-button cell phones and do not post their photos on the Internet.
Smartphone. Yin Fire. If Yin Fire is not good for you. Take aluminum foil. Aluminum, under the influence of a magnetic field, produces an electric current that creates a magnetic field opposite to the one acting. And it is not magnetized. Amagnetic. Like gold and lead. Be sure to turn off your smartphone. Wrap the smartphone and power supply in foil. Now you "don't" have a smartphone.
You can try with other things that are not useful to you. It is better to do it on days and hours of resonance of the element that is not useful to you.
At the same time, do not forget that the smartphone is not only a representative of the yin fire. This thing is a synchronization point.
! You must clearly understand what you are removing. The synchronization point or the element. !
In this case, the smartphone is two in one. What only you have can only be an element. What many people have is a synchronization point. Therefore, it is better to use individual things. Or make unique changes to what many have. Then it will become more the effect of the element, and less a synchronization point.
For relatives, the synchronization point is the bones of the skeleton. And for those still alive - partly the rest of the body

. Yin Feng Shui is a working topic. But I am not sure that it has reached our days without deliberately introduced changes. And checking is too high a risk.
