Sacred Sage Cleansing

So my wifes mother brought us some sacred sage (Zelda Item Obtained Music) I wanted to try it out and read online how to use it and asked my teacher on it.

You can use sacred sage to clear negative energy off almost anything I think, house, mendulums, crystals, person?

You lit the tip on fire and blow it out so you only get the smoke, kind of like incense stick. and walk around with it.

For the house you just walk to corners of the house then once you do that criss cross so it covers the entire room, did that for all my  rooms specially the ones I felt lots of negative energy...

How am I determining negative energy?... I dunno... just room that makes me feel bad... you walk in and you get like... man this room is icky... type of feeling...

Also did all my crystals and my wifes crystals + used sea salt + water to cleanse even more and tried to imagine pure white & gold light surrounding it with my energy. Tested on my A.A.Pendulum (AA- Aqua Aura) and it was moving more frequent than before it must be good thing. And yeah... that reminds me... fixed the damn pendulum top that came off... how? super glue to the rescue LOL

Also... used the sacred sage on my sword.... gotta make the sword holy! yeah its dull blade... but it can kill negative spirits... my secret weapon!
