Suffering Talks

Duḥkha ()(Sanskrit: दुःख; Pali: dukkha), "suffering", "pain," "unease," "unsatisfactoriness," is an important concept in Buddhism, Jainism and Hinduism. Its meaning depends on the context, and may refer more specifically to the "unsatisfactoriness" or "unease" of transient existence, which we crave or grasp for when we are ignorant of this transientness. In Buddhism, dukkha is part of the first of the Four Noble Truths and one of the three marks of existence. The term also appears in scriptures of Hinduism, such as the Upanishads, in discussions of moksha (spiritual liberation).

While the term dukkha has often been derived from the prefix du- ("bad" or "difficult") and the root kha ("empty," "hole"), meaning a badly fitting axle-hole of a cart or chariot giving "a very bumpy ride," it may actually be derived from duḥ-stha, a "dis-/ bad- + stand-", that is, "standing badly, unsteady," "unstable."
