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