Place the spirits seal, and/or the object in a triangle.
Envision a three sided pyramid of energy on the triangle.
This is your energetic “incubation chamber” that you’re going to empower the object inside of.
Call the spirit to help you, and oversee the operation.
Push energy and intent into this energetic structure however you see fit or whatever feels natural.
Try to program the energetic structure to pull the energy you want into itself and into the object like a sort of vortex.
When done, depending on the spirits guidance you might leave the object inside the triangle for successive charging(s), until done. (And bathing/impregnating the object with the energies)
You might place the object inside a jar, and burn a candle thats also charged on top of it (and/or tealights on the corners of the triangle).
You might also cover the object between charging a til it’s done (depending on the guidance or intuition you receive)
Follow your intuition.
