In addition to my own self, I know of many other people who have been used for target practice by covert operatives teaching or learning remote influencing, black magic, and related rituals and practices. How do we know? Well, some of us have spiritual gifts (aka psychic skills) that reveal the words and actions of these dark hearts (including telepathically picking up what the participants are saying).
Consciousness creates--either intentionally or unintentionally. Conscious intent creates energy. Directed energy often gets results--sometimes immediately, but sometimes after lengthy periods of time. So why not consciously create?
