I also teach the programming of stones which involves the discerning of the vibrations of emotion. I tell my students to hold each stone, one at a time, and try to project their thoughts into it. They are told to project a thought of a past happy event, and another a sad event. When they pick up these stones again to feel their vibrations, they notice that there is indeed a marked difference between the two. For the stone programmed with the happy memories, it is faster, lighter, livelier and more pleasant to touch whereas the one which encapsulated the unpleasant past has those heavier, slower and unpleasant vibrations. Some students may be moved to tears when they touch the unhappy stone.
