the unobtainable; that which cannot be known
Buddhist term referring to something that cannot be grasped or attained through ordinary means; often used in philosophical or doctrinal contexts.
In Buddhism, it is sometimes taught that truth is unobtainable.
From Middle Chinese 不可得 (pjuw khaX tok), meaning 'cannot be obtained'. The term is used in Buddhist texts to express the ineffability of ultimate reality.
