There are many ways of sending healing energy long distance to a recipient. I use the traditional Usui long distance method and remote viewing. Healing worked long distance can be much more powerful then healing work done in person because there is no mind that gets in the way. It's more powerful and much deeper and is usually experienced very deeply and powerfully as well by the one(s) receiving the healing energies and work.
The same way does psychic readings over the phone work. Consciousness and awareness can reach out into the grid and find anything, with keen perception. Even readings over the phone can be more profound and accurate since there is no personal energy field in the room with the reader, only the grid.
