IPA: /ˌætəˈræksi/
KK: /əˈtærəksi/
A state of complete peace and calmness, where one is not disturbed by emotions or worries.
After years of meditation, she finally achieved a sense of ataraxy that allowed her to face challenges with ease.
Ataraxy is derived from the Greek word "ataraxia" (meaning tranquility or peace of mind), which is formed from the prefix "a-" (meaning without) and "taraxis" (meaning disturbance or agitation). Thus, ataraxy refers to a state of being free from emotional disturbance or anxiety.
Think of being 'without' ('a-') any 'disturbance' ('taraxis') — that's why ataraxy means a state of tranquility.
