How do I use sage to cleanse my home and protect it from negative energy or spirits?

Name: Aman. DOB: 14 February 1993. POB: Lucknow. TOB: 6:10 PM.

I’ve tried reading about smudging online, but there are so many different instructions, and it’s confusing. I’m not sure about the proper way—like whether I need prayers, open windows, or specific motions. I don’t want to just wave smoke around randomly; I want to do it in a way that truly protects and cleanses my home from negative energies or spirits.
