To speak of "malefic energy" is a bit of a misnomer, though it's a convenient one. The energy itself isn't malefic, nor is it benefic -- the astral light, which is of course what we're talking about, is ethically neutral and carries good and evil intentions with equal facility. So a protective talisman of the sort I was discussing doesn't get rid of energy (which you can't do anyway), it disrupts and dissolves the malefic patterns in the astral light. Those patterns don't "go" anywhere -- that's like asking where the information in a data file goes when you hit "delete."
