The Black Quartz is a very important crystal for Night Magicians

The purest form of this mineral can only be found in Tibet, in the Himalayan mountains, and is considered one of the crystals with the highest vibrational frequency on this planet, probably due to his place of origin.

This crystal can be used in many aspects of the Night Magicians life.

It is a very powerful protection stone. It makes your Night Pillar stronger agains Yang or negative influences. It is a purifying stone: it will absorb all the negative energies around you, so it would be best to spiritually clean it quite often, or it will become counterproductive.

The Tibetan Black Quartz spontaneusly absorb and store Night Energy, making the Night Magician who's wearing it stronger and well protected.

It is said that this particular stone can speed up the spiritual and magickal growth, and helps to reach prticular mind or conscius states.

It helps with Astral travels and its vibration helps the unblocking of all chakras, but it is more effective with the Night Eye one (6th).

I don't have one yet, i'll order one via internet today or tomorrow at least, but due to my experience with other crystals i think the best would put one piece of black quartz under the pillow when sleeping. I normally place an amethist and the effects are incredible.

Always remember: it is best not to fall into New Age or Wicca teachings, but the crystals are part of the Earth. We also are part of the Earth.
Crystals really can help in spiritual growth, some of them can be used as catalysts for energy, Earth or Night Energy, charging your meditations and your rituals.
