It works via subspace, or the ultra-consciousness field that pervades the universe, also known as non-local reality. This process provides the ability to receive a session from a remote location.
Each individual has their own unique energy frequency which when connected into the system can reach anywhere in the universe. Like a cell phone, all that is needed is a sender, a receiver, and an exact frequency.
Frequencies transmitted via subspace often have the same accuracy as in an office visit. It is a preferable method for those individuals with a pace maker, pregnant women, or young children who are overly sensitive to energy.
