This is a more complicated version of the House Blessing Spell. However, it is generally more effective.
Salt and Water Incense (fire and air) Milk and Honey Oil (for anointing) Wine (for offering) Bells, Pots, Pans, Whistles, etc
Cast a circle in the main room (living room) and after casting, visualize the circle expanding to include the entire house. Call upon the spirits and energies living in the house (or apartment).
Invite those who will be harmonious with the new household and its energies to remain. Invite/ask those who will be happier elsewhere to depart. Release all “energies” not compatible with the new household. (This may be expressed as a “release” in order to unbind anything that may be stuck.)
Then call upon, greet, and invite ancestors, patron deities, and all harmonious spirits and energies to dwell in the house as they please. Gather up the pots, pans, and all the noise makers.
Go to each door and window, not forgetting the fireplace and dog-door, making as much racket as humanly possible–to shoo out anything unwanted. (This is hysterical fun, and also raises lots of energy for the next important step.)
Go again throughout the house and at each portal (door, window, etc.) sprinkle salt-water and incense, saying:
“By the Elements I purify and charge this portal.”
Then anoint the portal with milk and honey, saying:
“By Milk and Honey I ensure prosperity and peace within this place.”
Finally, anoint the portal with oil, saying:
“With Oil I seal this portal and protect all within.”
At the front door a special prayer is said, asking the guardian deities (God and Goddess) to freely grant entry to all friends and loved ones, and to prevent passage (turn aside) to any who would do harm.
Then, if it’s a house pour wine across the width of the threshold; if it’s an apartment anoint the threshold with light touches of wine. The householders then each take a sip of wine, leaving some as an offering to the Gods, and the Circle should be closed.
The remaining wine, milk, and honey should be offered to the Gods.
