The reference to "living water" is in the fourth chapter of Book 8-1.
Living Water is fresh spring water which has been exposed to the Sun for at least three hours in a wide-neck container made from wood or clay. The sunlight generates certain organisms in the water "which are indispensable to human life."
The water should then be placed in the shade for at least three hours. Only after all of these steps have been taken is the living water ready for drinking.
Vladimir Megre's son, Volodya, also explains the proper use of what he calls "dead water":
Dead Water contains little or no microbes. This kind of water is found deep within the earth and is relatively free of any bacteria. It is used to cleanse and rinse the body and intestines of harmful organisms and should be used before drinking the living water.
He also says that dead water should be consumed only when fresh, unpolluted air is present.
It is Vladimir Megre's opinion that most of the water being consumed by modern man is dead water. Adding living water to our diets provides us with the organisms that can only be created by the absorption of sunlight.
