Consecrate to what?
All a consecration is, is setting something apart by infusing it with specific energies. An altar “consecrated” to the Powers of Darkness, for example, simply has the energy of Darkness infused within it by the magician’s Will and intention.
The basics are pretty much the same: Fill yourself with whatever energy you want, imprint it with your intention, Will it to flow from you into the object you are consecrating, and seal it in through a simple “It is done.”
