Once a crystal has been cleaned, it is ready to use.
“Activating” your crystal is the idea of attuning it to your energy, but this simply isn’t the truth.
A crystal holds the same properties whether it is attuned to your aura or not.
It is you who attunes to the crystal, not the other way around.
Thus: you do not “activate” a stone, the energy synch commences from the moment the crystal makes its way to you. Interesting right?
To attune your energies to that of black tourmaline, you should keep it near you.
Put it in your pocket, place it near your bed, or just hold it for a while.
While you do so, use a little visualization to picture which of the crystals properties you would like to tap in to. And this is precisely why you are drawn to certain crystals on any given day, as they tell you, what you need or are feeling on the day as you magically seemed to be attracted to it.
