I like to use this chant that I wrote for blessing and cleansing my home. It is for the protection and well-being of the house and those in it. I hope you like it!
Bless this home and all within,
Mothers, Fathers, Children, Friends,
Keep safe and calm this hearth and home,
Never here let evil roam,
Protect this house from darkest sorrow,
Bless this home, now and tomorrow.
I like to chant this while going around my home smudging it with sage (or other incenses). This can be done every full moon, month, week, day, whatever you prefer.
