Chaotic Response Suppression is a type of Vulcan mental discipline. It is taught to young Vulcans as a way to maintain logical thought regardless of exterior interference and stimuli. The technique is divided into two phases: Phase One involves clearing the mind and calming the mental process, a process likened to planting a garden where logic can bloom. Phase Two involves the use of logic to evaluate the stimuli and other variables, and dismissing irrelevancies.
