I have healed a cow with an eye infection, a cat with an eye infection and my son who was born with a palsy arm. Using very, what seems, standard techniques.
Key is your vibe, if you are panicked and feel desperate, it does not seem as effective as if you feel confident and able to do this.
I used a visualization technique, while feeling very strong and feeling love for the patient, picturing the body healed. I spent what seemed like a day on the cow, feeding it grass, out by the fence talking to it, picturing its eye healthy, and it was healed by the following morning. The cat only took hours and a burr appeared out of the corner of its eye, and I was able to tweeze out the foxtail burr. My sons arm took a few weeks, but results were noticeable after about a week. I moved his arm in a normal movement way, while picturing my arm in his as if I was showing his body how to engage the muscles and arm. The palsy arm never returned.
So, know that it is totally possible and people heal all the time, with or without intervention from another. Every time you get a cut or a scrape, your body repairs and rebuilds, it is normal and best to think of healing as ordinary and easy to do.
That is my 2 cents worth.
