Lovely iconography on the wooden utensil[1] with a pair of people in comfortable looking robes and differing posture. Could this be suggestive of paired consumption or a guided experience? Could the void-like gap for face indicate ideas associated with possession or channeling, eg. a symbolic "not-self" or implication of self-departure? In the absence of additional finds, I suppose surviving modern shamanistic rites of the region might only provide minimal evidence toward a tenuous interpretation.
