Crystals in Vastu shastra

Crystals are such magical creation of nature, which attracts each and every one of us, possibly because of its sheen, formation, colours, or intrinsic designs & patterns. There would hardly be a person who would not be in awe of crystals. In veracity, it is not the beauty of the crystal which attracts our eyes but it is our bodily need of energies, which drives our liking for a particular crystal.
