Much as we wish we were not, even witches can find their days and nights disturbed by emotions we would rather live without. As such, if there is discord and distress in your life or your household and you need to draw in peace, then start by cleansing away the negative emotions from yourself, first.
Take a shower to cleanse your body and then fill a tub with some nice warm water, add in a cup of sea salt or Epsom salt. Stir to dissolve the salt into the bath, thoroughly, allowing the water to become even cooler as you stir. While you sit in the water, submerge yourself three times and just before going under each time repeat this chant:
God and Goddess bring to bear
Lasting peace that I can share
Fill me up from head to toe
Give me peace that all may know
Send all ill thoughts far away
Only good in me will stay
Create small sachets to hide in each room of your house. Include any or all of the following in the sachets: bay leaves, lavender, basil, and rosemary. As you place the sachets in each room, hide them well. They should not be seen or disturbed by anyone, on purpose or even accidentally. As you hide them in each area, recite this chant:
I bring peace into this space
Negativity I chase
From my home and by my will
Peace alone remains here still
From each room with each sachet
Negativity I slay
Only peace in here abide
With each person by my side
As always,adding layers through writing the spell on parchment, and including it in the sachet, adding stones, sigils, runes, pieces of metal, etc. to the sachet to meld the strength of other forms of protection with those stated above are entirely up to each witch. Only you can know what you need to do in order to serve your individual purpose.
Once you have completed these actions, remember to refresh the sachets as needed. Dependent upon how many people visit or live in your home and how much negativity tries to follow them into the house, you may need to refresh the sachets with new herbs weekly, monthly, quarterly or annually. How often is for the witch who lives there to decide as only you can know when you feel the need to replace them.
