The "Queen of Crystals" Amethyst is an incredible stone that can be used in many ways. It rules the realm of mind and spirit, providing a protective light shield around one’s aura to guard against psychic attacks as well panic episodes or addiction-related conditions because it helps conquer these things with its calming purple color which calms emotions down so you don't feel anything negative when meditating.
From Indian Philosophy, chakras are centers of spiritual power (energy) in the human body. The main chakras number 7 from the base of the spine to the crown of the head, although there are considered to be many secondary chakras within and outside the body.
