Energy is not limited to time and space. And once a practitioner is attuned to at least level 2 of Reiki, they are able to break through those barriers that most cannot comprehend through. I have been attuned to the Master level (level 3) of the basic Usui Reiki and two other types as well (Angel Ki and Kundalini). Personally, when I do distant Reiki for a client, I will send them a link to a frequency music to listen to that I will listen to as well at the time I do the Reiki for them. I will have them lay or sit back comfortably, arms and legs uncrossed, with no distractions, and receive the healing while relaxing and listening to the music. I will transcribe what the experience is on my end and send them the transcription along with follow up instructions when I am finished. I have had so many wonderful reports of clients experiencing exactly what I described during the experience. Energy healing is a beautiful thing!
