Many cultures have some form of tradition regarding space clearing and blessing ceremonies. Modern societies may have a house warming party. A business may have a grand opening or an open house to welcome in new energies for a positive business.
Space-clearing ceremonies release negative energies from the environment that can cause subconscious day-to-day discomfort. Blessings ask the ancestors to protect the space and establish an environment that encourages calm, joy and comfort.
Your preparation: Thoroughly clean and organize the land, building, home, or space. Air out the space by leaving windows open and letting fresh air cleanse the room for a good 15 minutes within 6 hours before the space clearing ceremony begins. Make sure the windows and sills are clean, too.
When I come to do the ceremony, we briefly have a conversation about the purpose then we together tour the space. I will work to clear and bless. I will give you the tools you need to keep the space clear so that you can do it yourself as needed. Fee dependent on the location and size of the space.
