The human and nature are inherently connected.
The oldest text about the healing power of crystals dates back to around 1600 BC. It is written on an Egyptian papyrus and indicates evidence of the use of crystals and stones as a remedy. Sick people wore beads of Lapis Lazuli, Malachite, and Red Jasper around their necks so that the disease could flow out of their bodies through the stones.
My first experience was with the power of Tiger Eye. All the immense tension I was feeling at the time flowed out of my body and was absorbed by the Tiger Eye. I was deeply impressed.
