In general, wouldn't burning sage just attract energies? I'd suggest casting a protection spell or perhaps a banishing spell to rid your house of it. Let me check my herbs, I'll tell you if any are good for smudging.
If it were me I'd cast a circle and use a mixture of sage and lavender to rid any negative energy from your house, and whilst burning the two I would declare that all negative energy be banished. That way anything that resides in your home that is not positive will be banished.
I hope this helps,
So, a good friend of mine has been seriously tormented by a demon for many years. I need to find a way to get rid of it asap. The biggest problem is, I haven't really done any magic before. What should I do...?
some people use techniques such as scrying, some people have familiars who will tell them information, some people are empaths with strong feelings that help them (feel) information, and similarly some people have advanced instinct/intuition that let them just know somehow ....
there are different routes and techniques that depend on your understanding of magic, your talents and gifts, and your skills, but in the end.
