When I travel, I would bring some of my crystals around apart from the crystals for CLT 5E Practice. During the night, I would place the crystals on the window sill (open air if possible) or on the veranda of the holiday resort so the crystals could be exposed to fresh air during the night after being worn the whole day.
I noticed on several occasions, insects (big or small) would land/perched on the crystals though some of the landings could be quite abrupt!!
I found out that later that when we carry the crystals around, we are helping to radiate the Creator’s love, provided it is not done out of fear.
