Tokmar
Tokmar was a Vulcan practice, which ancient Vulcans believed could bring lost souls back home.

After learning that Spock had dissapeared in 2257, Sarek immediatly began practicing tokmar every day in an effort to locate him. It took the form of sitting kneeled with his eyes closed, meditation-like, for hours. However, he was unsuccessful as Amanda Grayson had secreted Spock within a sacred crypt containing katra stones that blocked outside telepathic links.

Upon seeing her foster father perform Tokmar, Micheal Burnham remarked she had never seen it performed before. ()
