Vulcan teenagers go to Vulcan masters to learn the ways of logic and how to suppress emotion. For example, Tuvok was sent to study under a Vulcan master when he was a teenager and had rebelled against Vulcan discipline. (VOY: "Gravity")
Vulcan masters also preside over kolinahr when a Vulcan wishes to purge him or herself of all emotion. (Star Trek: The Motion Picture) T'Klass, a student of Surak, was one of the first kohlinar masters. (ENT: "Awakening")
