Here is a spell I created for blessing your home. I used sage while chanting this.
I invoke the old gods and goddess of long ago
I bring you from above here down below
Come here and come near thou shall encircle me
Shine your light onto my home I decree
Banish the evil and darkness that may lay.
Protect this dwelling night and day
The light now shall appear
Evil is kept out from here
Fill this home with warmth and love
Blessings be brought to us from above
Go now protectors and guides
Seal this home from all sides!
