Congrats on your new salt lamp, @zoe2! I LOVE Himalayan salt- I have some here for food and ritual purposes, but I constantly miss my salt lamp and candle holders (limited suitcase space when I moved to Europe ).
Aside from being absolutely gorgeous, it said that Himalayan salt lamps help to purify the air by removing negative particles and can enhance breathing and sleep.
One warning, though- real Himalayan salt SWEATS! It sucks out the moisture in humid environments and can make a drippy mess If you live in a humid place, consider placing a dish or small towel beneath your lamp.
Here’s a video from The Dancing Butterfly on YouTube about the benefits (including magick benefits) of Himalayan salt
