Having strangers in our homes can be difficult, but we can choose to treat their energy as an exchange of gifts as well as an exercise in acceptance.
Before their arrival, we can prepare by envisioning light surrounding our bodies and radiating outward from the core of our homes. We may want to create a calm and welcoming environment by playing meditation music or lighting incense. We can remove tension for all involved by putting away our valuables. Then when they arrive, we claim our boundaries by guiding them through their visit--asking them to remove their shoes, offering coasters or a place to set down tool boxes, and indicating by example to speak softly or not use harsh language. If something still causes stress, we can remember that what begins as an irritation to an oyster becomes a pearl. After they depart, we can burn sage and clear our space if we like but not without first finding the pearl.
Finally, remember that we learn about life by relating with others. People may have been sent to our homes because we ignored some of the universe's messengers outside. Our homes need not be a way to keep people out but can be the place where we are ourselves while accepting and allowing other's choices. When we share the joy of our homes, we radiate our light rather than hide it behind closed doors. The more we do this, the more the outside world can become like the sanctuary we've created inside.
