Ever since starting the process of creating and using my Heaven in a Bottle! essences, I have become ever more conscious of what could be lurking in the water I am using--either for consumption or bathing.This has resulted in some practical partnering with my angels in this area.
Now, before using water for drinking or cooking, I ask AA Michael to clear its energies, the Angel Amarushaya to put a blessing of light into it, and the Angel Raziel to clear any negative properties from the water's structure. This also applies to all other beverages, and liquids containing water. Aaaaaand to most of the food we consume. Water constitutes a large part of these things, too.
Taking a bath/shower, brushing our teeth or washing up are also good times to ask the angels to clear, bless and restructure the water coming out of the tap/showerhead. I was under the impression that the well water I am blessed with drinking would be filled with all kinds of good energies from the Earth--not so. Since I began clearing/blessing/restructuring the water I use, it has become clear that there is a need for this vigilance. I don't know what the source of the negative energy and structure in this groundwater is--I just know it's there and needs to be dealt with for my own peace of mind.
City water is bound to be even worse--try using the Angels and see if your health improves, or that of your family!
