The Khavorta posture was a component of Vulcan neuro-pressure. In 2153, T'Pol began administrating Vulcan neuro-pressure on Commander Charles Tucker III, who was having difficulty sleeping due to the death of his sister, Elizabeth Tucker, in the Xindi attack on Earth. T'Pol asked Tucker to assume the Khavorta posture during one of their sessions. (ENT: "The Expanse", "The Xindi", "Rajiin")
