Distance isn't an issue when doing energy healing, as we are all connected and the energy of the intention (like prayer) will go to where it is directed. By connecting to your energy field and muscle testing on your behalf we can then release imbalances energetically and with intention.
Healing is a personal journey and every trapped emotion, belief or other imbalance released will bring you closer to healing! However, if you wish to get to the core of the problem to be cleared you may need many more sessions.
There are many testimonials that describe incredible healings after just one or two sessions!
This is, of course, is sometimes the case, however, in my view it is also important to make it clear that every client is different, so unfortunately, it is impossible to say how many sessions will be required. Some people only require one or a few sessions to see a difference, and others need a lot more.
With any form of healing it is you and your body that does the healing when the imbalances impeding healing are identified and released, so commitment to healing is required.
Other factors to consider -
Every session makes a difference
Every session is important and makes a difference at some level. Some clients have hugely transforming single sessions but generally speaking several sessions are required to make a difference as the layers of the 'onion' are peeled back!
