cognitive distortion
Buddhist technical term for the four fundamental misperceptions: seeing impermanence as permanence, suffering as happiness, non-self as self, and impurity as purity.
In Buddhism, the four cognitive distortions are considered obstacles to enlightenment.
Older kanji form; 顛 is not a jōyō kanji, so 転倒 is preferred in modern texts.
From Middle Chinese 顛倒 (ten tawX, “to invert, to turn upside down”). In Buddhist usage, it translates Sanskrit viparyāsa, referring to fundamental misperceptions.
