T'san s'at
T'san s'at was the intellectual deconstruction of emotional patterns, the process by which Vulcans were able to control their emotions. It was a life-long process.

In 2373, Harry Kim asked Tuvok to teach him the techniques of t'san s'at in order to deal with his attraction to Marayna, then believed to be a holographic character. ()
