Zen is a variety of Buddhism that emphasizes meditation and insight into one's true nature. It was founded in China during the 6th century by the monk Bodhidharma and has since spread throughout East Asia and the West. ZEN is known for its focus on mindfulness and its emphasis on direct experience rather than intellectual understanding. It is also known for its use of koans, or paradoxical questions, to help practitioners reach a state of enlightenment.
