Gracey keep in mind that iridologists are not all equal. There are a lot of weekend coure people calling themselves iridologists who haven't got a clue about the
Science of iridology and not only do they give iridologgist who have studied it indepth a bad name but they do a disservice to would be clients.
When reading an iris, the results fall into two groups. Tendancies you were born with (strengths and weaknesses), and things that occur during your life.
Now seeing a strincture or a prolapse on the collarette, does not necessarily mean that you have one. This sign is there from birth and means you have an inherant weakness (you are prone to prolapse on the corresponding area). Knowing this you can then make changes to support the weakness so it doesn't happen or if you suspect it has (muscle testing can verify), then you can take measures to correct it.
It is also important to note (many semi-iridologists get this very wrong) that the markings that are from birth do not change. Think of them as a "soul contract" as you look into the windows of your soul. These are the things you took on and through free will, deal with.
Some changes that occur after to the iris, such as toxicity markings, can change for the better, but once the eye is scarred as it is blueprinted, the scar never fully clears even though the undelying condition is rectified.
THe other thing to note is that iridology reveals much more than just physical manifestations and tendancies, it can show emotional, mental and spiritual goings on. Its a powerful modality with proper knowledge and in the right hands.
A real holistic irridologist studies for several hundred hours and takes a very scientific approach to reading your irisis. Most also have several other important modalities under their belt before good integrated advice is given.
If you want to study from the absolute best in the world, seek out Dr. David Pesek who is the leader. He was
Bernard Jensen 's protege and took the baton from him. There have been many more insights gained since Bernard's time. My wife has just been certified as an International Holistic Iridologist under Pesek. There is no finer acreditation in the world for iridology today.
