I have had a chance to look at this Kapala (Tibetan ceremonial skull) up close. These are used for higher tantric levels to achieve transcendental state.
Within the skull I found rolled up and bound cardboard for stabilizing with Nepalese writing on it.
As a psychometrist, I can say that I was thrilled to get a chance to visit with this and get a read on it.
It is best described by energy interpretation -
It is a black soundless wind, very masculine energy, and would make an ideal astral projection activation device.
To some, these are idols and catalysts for a spiritual journey to others antiquated primitive genie lamps.
To me, it is a dense concentration of much meditation and many higher states of mind and that creates a very powerful tool.
I would like to thank the researcher who allowed me to hold and examine it.
