hi, i've been thinking.
someone posted a while ago saying white sage (burning incense or spraying it in a bottle) will clear a room/house of spirits.
i was just wondering.
what is it about white sage that does that?
i mean, do ghosts find the scent offputting, does it do something to their vibrational energy field?
for that matter what do smudge sticks do that make them 'cleanse' a room.
and while i'm on the topic, how is it that crystals can have an affect on you?
do they emit something?
is it like sitting in front of a microwave?
how does it actually work.
cheers in advance.
