T'san s'at

T'san s'at is the intellectual deconstruction of emotional patterns, the process by which Vulcans are able to control their emotions. It is 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.
