How do you keep negative energy out of your house ?

[Alokina]

A candle is a simple way to activate the element of fire in your home or workplace. A candle flame can absorb and burn heavy energies, it is a powerful healing energy. Cleanses, inspires, helps release everyday stress,
Fragrance can lift the atmosphere in a space and also protect it from negative energies and bad influence. It can clear the space, reboot and immediately raise the vibration to a higher frequency. It also protects and acts as a repellent to low energies and provides a supportive atmosphere.
Ventilate, open all windows and doors, open the curtains and let the energy flow.
Clean up, yes even normal cleaning and organizing things breaks down stagnant energy.
Get rid of what you no longer need, what you haven't used for a long time and what you probably will never use.
Get rid of broken and damaged items or repair them.
Move the furniture and its placement, low energies need something immobile to cling to. The space should be as wide and open as possible so that harmful energy can dissipate.
Live plants - placing live plants in your premises will purify not only the air, but also the energy.
Dance - dancing around the apartment and all its corners, and preferably with loud singing, will not allow heavy energies to remain in your homes.

Lots of good advice in this thread so far! Here's another one: I "sweep" the negative/stale energy out. You don't have to literally sweep literal dust, but use sweeping motions while intentionally visualising the yuck clearing out of your space. I just use a normal broom or handkerchief right now, but I want to get a proper besom eventually for this purpose, since it's easy and feels like one of the most effective methods for my space, vibes, and lifestyle!
