Word of warning. Isis tricked Ra in giving her his real name and she used it to bring Horus into life. As a consequence her consort Osiris was slain, cut in 14 pieces, scattered across the land, and emasculated. A death for a life. But wait, this happened before she used the power of Ra his true name. Understand, time is not linear, does not exist in the outer void. Cause and effect does not follow our linear time. Using this 'magic' for a better term comes with a high price. True no karma as such, just cause and effect. Equilibrium. Plenty of people have unwittingly destroyed themselves. Spending their existence in places you don't want to know.
