These codes are quantum healing tools that are safe to use on everything and everybody, and have no side effects. Since they are quantum, the intent and the energy of the person using them have a little bit of ‘effect’ on how powerful they are going to when they are used. In the hands of someone with a powerful heart energy–which has more to do with your strength of purpose and your ability to be actively involved in your Life’s Mission and connected to source than anything else–they will work.
