When crystals grow into specific shapes, they bring the energy to bear along the lattice. This makes each crystal contain potential energy that can be invigorated by intent.
Intention is the focusing of mental energy by a person on a particular crystal. You can hold and rub a crystal to make it your own as your own internal energy crosses from your aura into the crystal. The longer you own a crystal, the stronger it becomes.
Not all crystals are made from the same elements and different crystals are good for different things. to tap into the healing powers of crystals you need to understand the meaning of each crystal and which dynamic energy and elements it can bring forth.
