| | Effectively Clearing Your Home
It sounds like others have addressed clearing your personal energy to some extent.
I would like to offer a house cleansing ceremony that was very effective for removing some "little friends" who tagged along with a houseguest we hosted. My housemate and I were up all night with violent dreams and later realized we had been slowly gravitating away from love for the duration of this individual's stay. Fortunately, this ritual, which my Reiki master offered to me, was very powerful and effective.
Set sacred space however you do. I work a lot with the medicine wheel, so I called in all my allies and the different elementals and such, and I charged the entire ceremony with Reiki. Do what feels right to you.
Begin with a prayer of intention calling on enlightened beings, your guides, angels, your higher self, the ancestors, etc. to come help you sanctify your home. State that you now intend to allow only beings of the highest light and loving vibration to enter your home, and ask them to help you remove anything that is other than that. Ask that they create a bridge of light to help any beings who do not resonate with pure love and light to cross over to a different home. Definitely add any personal intentions as the spirit moves you.
Grind up and burn dragon's blood resin. This is very effective at removal of "the nasties." Starting at your front door, circle your home counter-clockwise, blessing every corner, every nook and cranny, with the smoke. Visualize feelings of relief, of joy, of love. Go through the entire house this way. The more smoke, the better!
Then open the windows and doors and let it air out a bit. Imagine all the gunk leaving.
Next step is calling in the beauty. Beginning at the front door, circle the home clockwise while smudging everything with sage. This is your opportunity to visualize your sacred space and bring in everything you want to experience. Feel free to speak your affirmations of abundance, pleasure, service, gratitude, or whatever out loud and to be quite playful. Go through the whole house, then let it air out again.
Thank your guides and offer the merit to all sentient beings, if you are so inclined. Close out your sacred space and enjoy your new home!
