You need Tiger Eye if you are currently overthinking and mood swinging, or you are a Gemini or a Virgo. Put it in a string of prayer beads, hanging from your middle finger, counted during meditation, along with your blessings. Use Tiger Eye when your thoughts are not your friends. When reading Jungian theories or attempting to decipher a Zen koan. When only equanimity of mind, body, soul, left brain, and right brain can get you square with the universe. When you are all roar and not enough purr. Balance your whole being.
