The stone can preserve the force almost indefinitely. There are those stones which can serve as a link, there are stones which can serve as a battery.
There are stones which can hold a force for protection. That indeed is remarkable, my child.
One can accumulate in a stone (particularly in amethysts) a force for protection, and the force truly protects the one who wears the stone. It is very interesting, I have experienced it.
I knew someone who had a stone of this kind, charged with the power of protection, and it was wonderful when he wore it.... There are stones which can be used to foretell events.
Some people know how to read in these stones events which are going to happen. Stones can carry messages...
The Mother19th August 1953When you pick up a stone and look at it with your ordinary eyes and consciousness, you say, "It has no life, no consciousness."
For one who knows how to see behind appearances, there is, hidden at the centre of this Matter - at the centre of each atom of this Matter - there is, hidden, the Supreme Divine Reality working from within, gradually, through the millennia, to change this inert Matter into something that is expressive enough to be able to reveal the Spirit within.
Then you have the progression of the history of Life꞉ how, from the stone there suddenly appeared a rudi-mentary life and through successive species a sort of organisation, that is, an organic substance capable of revealing life. . . .
The Mother 23rd October 1957A spiritual evolution, an evolution of consciousness in Matter in a constant developing selfformation till the form can reveal the indwelling Spirit, is then the keynote, the central significant motive of the terrestrial existence.
This significance is concealed at the outset by the involution of the Spirit, the Divine Reality, in a dense material Inconscience; a veil of Inconscience, a veil of insensibility of Matter hides the universal Consciousness-Force which works within it, so that the Energy, which is the first form the Force of creation assumes in the physical universe, appears to be itself inconscient and yet does the works of a vast occult Intelligence.
