Black Tourmaline crystals offer psychic protection for anyone who must work or live in challenging places or circumstances. It can keep one’s auric field clear of imbalance even in the presence of destructive energies. Black Tourmaline crystals act like etheric vacuum cleaners, clearing oneself and one’s surroundings of negativity and disharmony.
Another application for Black Tourmalines is etheric purification. Carrying one of these stones in the pocket, holding one in meditation or sleeping with one in the pillowcase will provide a refreshing dose of cleansing for the auric field and the etheric body. This clearing can even echo down into the physical form.
Black Tourmalines are also recommended for ridding oneself of negative thoughts, anxieties, anger, self-judgment and ideas of unworthiness. A small number of Black Tourmalines are double terminated. These are the ideal specimens for body layouts because the linear flow of energies is enhanced equally in both directions along the crystalline form. Healing practitioners who utilize crystals are especially advised to use these with their clients.
