The hole in the iris shows that those organs of the human body are weak (acquired and congenital)!
The internal organs corresponding to the cracks indicate that the function of internal organs has begun to fail and there has been an uncomfortable reaction, which should be prevented and treated as soon as possible!
The human eye is the holographic reflection area of the human body, and all organs of the human body can be displayed on the eyes. Iris has been used in western countries for a long time, but it is still used less in China, and few people know it!
At present, there are few books about iris in China. I recommend you to read the book "Observing Iris to Know Health", which is very detailed and accompanied by dozens of cases! If it is not convenient to buy books, you can also go to Youku to search for "Iris". There are some lectures on the basic knowledge of iris, which can give you a preliminary understanding of iris! If you want to study deeply, you have to find professional training (well, I'm looking for professional training, but at present many of them are certification training. What can I learn in about 2 days? )
