anatta, in Buddhism, the doctrine that there is in humans no permanent, underlying substance that can be called the soul. Instead, the individual is compounded of five factors (Pali khandha; Sanskrit skandha) that are constantly changing. The concept of anatta, or anatman, is a departure from the Hindu belief in atman (“the self”). The absence of a self, anicca (the impermanence of all being), and dukkha (“suffering”) are the three characteristics of all existence (ti-lakkhana). Recognition of these three doctrines—anatta, anicca, and dukkha—constitutes “right understanding.”
