The Twins is a double faced ancient jade skull, also found in the same tomb or temple in Mongolia
as As-K-Ra, Jade and other jade skulls. Difficult to ascertain how old they are, they do hold a high vibrational energy and I feel they are like a pair of cupids!
The Twins have shamanic masks carved on their third eyes, similar (but not the same) as the shamanic masks carved on every bone of AsKRa. Like the large jade skulls this piece is hollow, with same details like nose holes and the discs either side.
The Twins are a wonderful companion on shamanic journeys, as you always have someone looking out for you from behind! I am sure this was one of the reasons for their creation. Another aspect for healing is their ability to assist in healing internal conflicts and elements of duality that we all have!
