"Since time immemorial, crystals and precious stones (along with flowers) have held special significance for the human spirit. This significance can be attributed to their etherial quality. When you contemplate them without naming it mentally, it becomes a window for you into the formless. There is an inner opening, however slight, into the realm of spirit. These life-forms have been preparing the ground for a more profound shift in planetary consciousness that is destined to take place." - Eckhart Tolle
