Apophyllite
Apophyllite is used as an aid to meditation and helps us make a conscious connection with the spiritual world. It has been used to help in mind over matter (eg fire-walking) and astral travel.
It helps us see the truth and how to act on it. As an energy stimulator, it is a wonderful stone to use when generating other crystals. It relieves tired eyes when placed on the eyelids.
When placed on the third eye chakra, it enhances clairvoyance and mystical vision. Apophyllite is also associated with the crown chakra.
