During a healing period, you will also expierence your body will release a lot of (old) emotions that might have been creating blockages in your life.
Often I hear that people get little signs during the healing period because the energies want to leave your system. (like feeling hot and cold, sweating, or other small ways for our physical bodies to release emotions, stress and things like that).
It will take me a week to do a photo healing. I will be healing through your picture on daily basis for a whole week. After 3 days, you will start to notice changes in your energy. (often the first days it is all about release and the days after that, you will feel more energized again).
I have Reiki and many other skills that I have learned over the years, but for the photo healings I will always let the source energy flow through me. So it will always be from a high frequency with my intentions by heart.
This is possible for children as well. Especially highly sensitive children, or children having sleepless nights can benefit from this. I hear great results from the parents by balancing energies with sensitive children.
