Gemstones and Public Buildings
For example if a gemstone can absorb and neutralize "negative" energies then it would be ideal to place in prisons and other places where negative energies tend to accumulate. Due to the law of sympathetic vibration and other factors the inmates of prisons are often more suseptable to negative vibrations than the general populace.
Such negative vibrations tend to encourage criminal thoughts and behaviour etc and interfere with the rehabilitation and the inner healing of the inmates.
If the skillful placement of specific gemstones (along with a range of other techniques) can uplift the energy in prisons, by even a small amount then the overall beneficial effect on society would be significant.
Other examples include:
Calming and healing gemstones in hospitals.
Concentration and creativity gemstones in new-style schools and research labs.
Detoxicifaction, sobriety and willpower gemstones in places designed to help treat addicts.
Gemsones giving a peaceful and loving atmosphere in places that are conflict flash points.
If sections of the wall materials were mixed with small fragments of gemstone, that would have an effect. Doorways may have a specific bar of more high grade gemstone hidden along one of the edges of the entrance. Food, wash, and sleep areas would also have a higher concentration of the beneficial gemstone. Symbolic placements of the gemstone also have value so placing gemstones in the foundations of the buildings, in the corners and the cardinal directions is considered useful.
