Koan
/KOH-ahn/
A koan is far more than a mere riddle; it's a potent spiritual device in Zen Buddhism, a paradoxical anecdote or question designed to utterly derail intellectual thought. Presented by a master, it challenges the student to transcend conventional logic, pushing them past dualistic thinking into a direct, intuitive grasp of reality. The goal is to shatter preconceived notions, leading to a profound, often sudden, moment of satori or enlightenment, revealing truth beyond words.
Lit. Public case / law case
Used within Zen Buddhist traditions to guide meditation and spiritual practice, often presented by a master to a student.
