Mumonkan

The Mumonkan, also known as the Gateless Gate, is a highly influential collection of Zen koans compiled by the Chinese Zen master Mumon.

These koans, paradoxical riddles, are used in Zen practice to challenge the intellect and provoke enlightenment.

The Mumonkan is not merely a collection of koans but also includes Mumon's insightful commentaries on each case.

These commentaries offer guidance and interpretation, helping practitioners navigate the complexities of Zen practice.

The book has been translated into numerous languages and continues to be a cornerstone of Zen study worldwide.
