Firekeeper,
Namaste,
Actually, it is somewhat in the same league as what I was thinking about, which involved some involuntary rap music into earphones for at least 12 hours. :oPPP
I think crystals are pretty much already programed for the activity, just not necessarily the person using it. It might not be so much programing the crystal, as programing ourselves to use it in the proper (for it) manner.
My obsidian ball (small) seems to really dislike being used by other people, for instance. Loaned it out once (long ago) and it was very distant for weeks. Or maybe it had just been programed to her, and had to be re-programed. what do you think?
Love and Light,
Priestess
