Black Tourmaline offers psychic protection for anyone who must work or live in challenging places or circumstances. It can keep one's auric field clear of imbalances even in the presence of destructive energies. Black Tourmaline crystals act like etheric vacuum cleaners, clearing oneself and one's surrounding of negativity and disharmony. Another application of Black tourmaline is etheric purification. Carrying one of these stones in the pocket, holding one in meditation or sleeping with one in the pillow will provide a refreshing dose of cleansing for the auric field and the etheric body. This clearing can even echo down into physical form. Black Tourmaline are also recommended for ridding one's self of negative thoughts, anxieties, anger, self judgement and ideas of unworthiness. A small number of black Tourmaline are double terminated. These are the ideal specimen 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.
Black Tourmaline's protective energies are enhanced by combining it with Jet, Obsidian, Black Andradite Garnet, Smoky Quartz, Sugilite, Charoite and Amethyst. Its grounding can be increased by Hematite.
