Hip Glossary: Koan

koan A story, question, problem or statement generally inaccessible to rational understanding, yet may be accessible to Intuition. Koans originate in the sayings and doings of sages and legendary figures, usually those authorized to teach in a lineage that regards Bodhidharma (c. 5th-6th century) as its ancestor. Koans are said to reflect the enlightened or awakened state of such persons, and sometimes said to confound the habit of discursive thought or shock the mind into awareness. Zen teachers often recite and comment on koans, and some Zen practitioners concentrate on koans during meditation.
