Suffering Talks

Duḥkha (; Sanskrit: दुःख, Pali: dukkha) lit. "suffering", "pain", here "restlessness", "a sense of unease, dissatisfaction, or incompleteness", is an important concept in Buddhism, Jainism and Hinduism. Its meaning is context-dependent: it may refer more specifically to the (sense of) "unsatisfactoriness" or "unease" of craving for and grasping after transient 'things' (i.e. sensory objects, including thoughts), or expecting pleasure from them while 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).
