In Buddhism, acinteyya (Pali), "imponderable" or "incomprehensible," avyākṛta (Sanskrit: अव्याकृत, Pali: avyākata, "unfathomable, unexpounded,"), and atakkāvacara, "beyond the sphere of reason," are unanswerable questions or undeclared questions. They are sets of questions that should not be thought about, and which the Buddha refused to answer, since this distracts from practice, and hinders the attainment of liberation. Various sets can be found within the Pali and Sanskrit texts, with four, and ten (Pali texts) or fourteen (Sanskrit texts) unaswerable questions.
