I remember reading in a Kushi book, about Ohsawa doing some tests and construction some home made system, that energized the water, like it would be energized in the free nature.
I was very interested about knowing more of this thing.
It was assembled from real rocks and other nature elements I think.
And the result water was high in energy (chi).
Does anyone heard about this too? I can't remember which book was it posted in.
Any more info?
