Space
Here are 6 potent space healing techniques:
๐ฅ Incense (including copal, palo santo, ...)
๐ฅ Candles (those tiny white teacup candles are powerful!)
๐ฅ Crystals (my favorite crystal right now is Shungite)
๐ฅ Smudging (this modality has become quite en vogue in the past years)
๐ฅ Altar building (I am quite confident that you've got altars around your home already)
๐ฅ "Feng shui" (also known as the Chinese science of placement)
