The Himalayas, Tibet, where these crystals are found, is one of the most sacred regions on earth, and Tibetan 2-ended quartz crystals are among the most powerful stones found for spiritual protection.

Sleeping with Tibetan Quartz or near Tibetan Quartz protects from lower astral energies and can help eliminate disturbing dreams. keeping a stone or several of these stones in a space can purify this space and make negative influences disappear, this Tibetan quartz is even recommended to put it above the television screen or the computer in order to counteract the disharmonies which could emanate from it.
Meditating with a Tibetan quartz can be very beneficial, especially for those who feel an affinity with Tibetan Buddhism. 
A silent "om" seems to emanate from this stone at all times, and it can powerfully activate the third eye. It also resonates with the state of silent attention that is essential in meditation.
Besides offering protection and purification, Tibetan quartz can activate and balance the chakras and meridian systems. If one of the chakras or nodes is blocked or too slow, touching that point with a stone can quickly fix the problem.
Tibetan Quartz harmonizes with Moldavite, Lithium Quartz, Aegirine, Black Tourmaline, Nuummite and Shamanite. Combining these stones with any truth of azeztulite will bring in angelic energies.
