This reminds me of a dream a close friend of mine shared last year, in it she saw me healing people with subtle energy from the hands, as well as purifying food and water to transmute it to living energy before it was ingested. She had prior to this dream read a book that suggested such and urged me to try it. The book envisioned that certain people within the communal village would infuse the water with subtle energies directed through their hands. This would work small scale as well as larger, something like simply blessing the water. The author indicated that certain people can do this easily by starting with a small glass of water.
