Also known as "Liquid Light", Selenite, is a great stone to have in your collection. It connects with your third eye and can help align all of your chakras. It needs little upkeep and essentially charges itself and other stones if placed on it. Another great benefit of selenite is it helps clean your aura.
Palmstones are great for meditating with or sitting and setting intentions. The beautiful etched Om design helps to remind you of the ultimate reality, or consciousness. "Om" is the most sacred mantra in Hinduism. Simply hold this while meditating and repeat, "Om" (Pronounced like "hOMe"). Or if you are skilled in this you may decide to recite, "Om Mani Padme Hum".
