Sage burning to cleanse an area and alternatives?

[AnthroHeart]

My teacher and I put up bags with crystals, lavendar and other stuff in the 4 corners of the house and imagined a wall between them.
It forms a barrier that keeps out negative beings from the home. I still will cleanse with sage from time to time for negative energies.
I just know that negative beings don't like sage. It repels negative energy and leaves a neutral energy behind.

I would purify whenever it gets heavy or too dark feeling.

My teacher said to keep a outside door open when doing it. Though you could do a window too I imagine.

Holy Water is also of high vibration.
